Description

Portable diet manager

The present invention relates to a personal information terminal for weight control, which relates to a portable diet manager for measuring and monitoring changes in real time such as food intake and exercise (movement).

In general, obesity is a phenomenon in which excessive calories are accumulated in fat in the body when the calories ingested are larger than the calories consumed in the body, which causes various diseases such as hypertension, diabetes, and cardiovascular disease.

Obesity usually means overweight, but stricter concentrations of fatty tissue in the body are more concerned with secondary complications, so attention should be paid to the diagnosis and treatment of obesity as well as to the presence of other pathological conditions.

Conversely, eating too much calories to gain weight can have a negative impact on your digestive system and skin, rather than on quantitative changes.

As such, many people lose confidence or stress because of their appearance and interfere with social life. It is investing a lot of money and efforts economically, and products and advertisements are pouring out to lose weight.

However, many people fail to control their weight in an attempt to lose or gain weight in a short period of time without accurate knowledge, and do not lose weight by exercising unconditionally.

In other words, a diet that maintains a healthy normal weight is more scientific and deliberately practiced under the very natural principle of proper diet and exercise that fits the amount of self-activity. And accurate analysis is required by real-time check of personal activity information and exercise information.

In particular, there is a need for personalized management to provide calorie information related to food and meal information related to weight / health.

The control means 10 determines whether the user is walking or exercising by comparing the number of pulses output from the exercise amount detecting means 90 with a preset reference number, and then, by accumulating the number of pulses, calorie consumption according to the number of pulses. A central processing unit that calculates the amount of exercise in comparison with the stored comparison table. The control means 10 is internally composed of a control device, a controller storage device, a register, an ALU, a main memory interface, and the like. In microprocessors, which consist of circuit boards, a microprocessor chip consisting of a Very Large Scale Interface (VLSI) performs the function of a central computing unit.

The interface means 20 is an external interface for data communication and data reception using a computer. The interface means 20 is used as an input window of an intermediate terminal that can be connected to an arbitrary input means. It is a means of connecting two pieces of equipment by specifying the necessary requirements for the interface or the connection between two different devices or circuits. In other words, the connection between the two systems or equipment such as connection, interface, diet manager and computer, diet manager and communication line, such as IEEE-488, RS-232C is used.

The first memory means 30 is a ROM that can only read the data once it has been written and cannot be changed later. The first memory means 30 does not erase the contents even when the power supply is turned off or the battery is replaced. Save it. It stores contents or programs necessary for manufacturing in a read-only memory so that the bootstrap loader performed when the user turns on the diet manager or configures a general environment.

The second memory means 40 is an SRAM (Static RAM) that can be accessed within a certain time regardless of the location where the data is stored. The second memory means 40 integrates flip-flops and maintains contents while the power is turned on. It can be used as a main memory because it can increase the storage capacity without the need for regeneration, and access is much faster.

The key input means 60 is mainly a hexadecimal or numeric input keyboard, personal identification information (gender, name, password, key, date of birth, weight, body type, smoking degree, menstrual cycle, body size, drinking amount, blood pressure, (Feeding relationship, etc.), and set the target body weight, target date, etc., and choose the type of food and rhythm (eEG), numbers (0), dot (.), Comma (,), plus (+). ), Minus (-), function key (Fuction), direction key (Direction key), enter (Enter) and the like.

First and second amplifiers 91 and 92 to amplify, an adder 93 for adding two shock signals amplified by the first and second amplifiers 91 and 92, and an impact added by the adder 93 The comparator 94 outputs a constant pulse waveform by comparing the signal with a reference value.

Hereinafter, the effects of the portable diet manager configured as described above will be described.

When the diet manager is turned on, the items of the initial personal information to be input by the user are displayed through the display means 50.

Accordingly, the user manipulates a plurality of keys (for example, numbers 0-9 and dots, commas, etc.) provided in the key input means 60, and according to the items displayed on the display means 50 according to gender, name, password. Enter general personal information such as height, date of birth, weight, body type, smoking level, menstrual cycle (date, cycle), body size (chest, waist, hip, etc.), drinking volume, blood pressure, lactation.

A convenient calculation formula commonly used in clinical practice is (height-100) × 0.9. For example, if you are 170cm tall, (170-100) × 0.9 = 63kg is ideal. However, this method tends to increase obesity in shorter people and less obesity in taller people.

Therefore, the diet manager calculates the body mass index of the user by the body mass index calculation method (BMI) based on the data input by the key input unit 60 as follows.

Body mass index (BMI) = weight / (height) ²

If the body mass index is 22 for both men and women, the mortality rate is lowest. The higher the index, the higher the mortality rate, but the lower the mortality rate. Generally, between 25 and 29.9, overweight and over 30 are defined as obesity.

As described above, the diet manager for diagnosing obesity based on the initially inputted information data displays the current state of the user by dividing 110-120% of the abnormal weight into overweight and 120% or more into obesity. Through graphic, text, or character display, a database can be established based on data and plans related to it, so that a target for weight loss can be set within an arbitrary period.

Therefore, when the individual loses or maintains the weight or plans to increase the weight, he / she selects a current weight target amount and a target date by operating a diet function key provided in the key input unit 60.

When the weight target amount and the target date are selected as described above, the control means 10 according to the data stored in the first memory means 30 according to the personal or diet target information (food and food calories accumulation amount, exercise type and Calorie consumption according to exercise, etc.) is displayed through the display means 50, so that calorie information of daily life and consumption / accumulation are provided in real time.

When the diet information of the daily food and exercise amount is provided as described above, the user takes the food according to the provided diet information and adjusts the exercise amount as follows.

First, the user does not eat food or exercise (swimming, tennis, etc.) without wearing a diet manager, and then presses the food key (FOOD) provided in the key input means 60 and presses the menu key (MEN). When operated, the type of food and its amount and calorie information are displayed. For example, Korean / Chinese / Japanese / Western food or meat, fish, vegetables, instant foods, etc. are divided into large classes, and according to the middle class, the types are subdivided and calories according to detailed food names and amounts are provided.

In this menu, you can enter your planned weight and duration, and you can memorize the type and amount of meals you do frequently in your home or outdoor location, so that you can enter the desired items in addition to providing a database of the types of exercise and food types available. It is.

In other words, the type and definition of exercise provided by the diet manager is set to implement a proposal suitable for maintaining the body shape considering the characteristics of each part of the body. Basically, the diet manager provides the type of physical exercise and calorie consumption from the stored database, but can be newly input by user definition. Therefore, the diet manager basically provides the type of exercise, time, and calorie consumption. The type indicates the type of exercise that you like and the exercise that can be performed within the planned period.

There is a menu check box in the main menu so that when the user selects food for food control, the calories for the selection menu are provided. Alternatively, if the user selects a proper classification for the desired calories, a food menu that approximates the input calories is provided. Therefore, the user can easily know the calories of the menu selected by the user, and can be provided with the menu for the calories required.

In addition, the main menu stores the records from the first attempt of the diet carried out so far to the present carried out to obtain information on the diet carried out at any time.

Therefore, the control means 10 can display the calorie accumulation / consumption amount in real time according to the amount of food and food ingested by the user or the amount of additional exercise according to the type of exercise (swimming, tennis, etc.) while modifying the user's diet goal. Provided by.

Next, when the user carrying the diet manager (which can be worn anywhere) is walking, running, or exercising, the function of monitoring physical exercise amount is performed by performing calculations appropriate to the user's constitution according to the interval and impact degree for stride length. Every calorie consumed is differentiated. In particular, the user can monitor the progress at any time to effectively control the diet.

That is, when the magnitude of the waveform finally detected by the two impact sensors c ₁ and c ₂ installed in a direction perpendicular to the PCB (not shown) embedded in the portable diet manager is shown in FIG. 4, When the acceleration of A is applied in any direction,

Sc ₁₊ c ₂ = Sc ₁ + Sc ₂ (c ₁ : sensitive to vibration in yz direction, c ₂ : vibration in xz direction).

Sc ₁₊ c ₂ = {acceleration in y direction × cosθ ₁ + acceleration in x direction × cosθ ₂ + acceleration in z direction × (sinθ ₁ + sinθ ₂ )}

= Aycosθ ₁ + Axcosθ ₂ + Az (sinθ ₁ + sinθ ₂ ).

Therefore, when vibration is applied only in the direction of x, Ay = Az = 0,

S = Axcosθ ₂ ,

② If vibration is applied only in the direction of y, Ax = Az = 0,

S = Aycos θ ₁ ,

③ If vibration is applied only in the z direction, Ax = Ay = 0,

S = Az (sinθ ₁ + sinθ ₂ ).

As described above, when signals of the waveform shown in FIG. 5 are finally detected by the first and second shock sensors c ₁ and c ₂ for detecting vibrations applied in three directions of x, y and z, the first and second shock signals are detected. The low frequency band of the signal detected by the shock sensors c ₁ and c ₂ passes through the _first and second low pass filters LPF1 and LPF2, respectively, and is detected by the _first and second shock sensors c ₁ and c ₂ . The high frequency band of the signal is passed through the first and second high pass filters HPF1 and HPF2, respectively, so that only the waveform of the Fw section shown in FIG. 5 is passive.

The waveforms of the Fw sections passing through the first and second low pass filters LPF1 and LPF2 and the first and second high pass filters HPF1 and HPF2 are amplified through the first and second amplifiers 91 and 92, respectively, and then added to the adder. The two shock signals added through 93 are added to the comparator 94 to output a constant pulse waveform according to the comparison result with the reference value.

The pulse output from the comparator 94 is input to the control means 10, and the control means 10 determines whether the user is walking or exercising by comparing the number of input pulses with a preset reference number. By accumulating the number, calorie consumption according to the number of pulses is compared with the stored comparison table to calculate the exercise amount.

Therefore, the control means 10 displays the calorie consumption according to the calculated exercise amount and provides the user's diet goal as a menu that can be modified.

As described above, the calorie accumulation amount and the consumption amount are displayed in real time according to the amount of food and food intake, the amount of exercise and the amount of exercise according to the type of exercise, and the status of change in diet loss or weight loss of each day is determined separately. Display them using characters (apples, people, animations, etc.).

That is, the Kauf index, which is the body mass index, is displayed as a bar graph or a nonlinear quadratic (or cubic) graph, which is an arbitrary index, to display the target graph fidelity and the plan line according to the current user's effort. It will show you your plans and actions according to the Kauff Index.

At this time, if the user consumes more calories than the calorie consumption according to the target, the control means 10 generates an alarm sound through the alarm sound generating means 100 to warn the user to stick to the diet goal.

In addition, when the user plugs the earphone into the jack 83 at bedtime or exercise, and selects the desired brain wave (rhythm) by operating a separate rhythm selection key provided in the key input means 60, EEG generating means (80) In the amplified sound source stored in the first memory means 30 in accordance with the control signal to the control means 10 and outputs through the jack 83, the user can hear the brainwaves suitable for sleep or exercise.

EEG signals are transmitted between brain neurons. It refers to the wavelength generated when the electrical flow occurs, and it is known to have an important effect on health, and brain waves include delta waves, theta waves, beta waves, and alpha waves.

As described above, the user can live while listening to the EEG suitable for bedtime or exercise to enable the use of more effective devices while maintaining health.

In addition, the user can continuously update the food menu for the diet, the type of exercise and information, etc. periodically or aperiodically by performing data communication and data reception using a computer through the interface means 20.

Other additional features include emotion, intelligence, and physical biorhythms to provide a constant rhythm curve through the activities of human life. The basis for the data is based on the date of birth of personal information. In addition, it can be added to the calendar, calculator, address book, and other information notebook functions, which can be a necessary device for users. In addition, since the basic calorie consumption of the user's breathing and acting is about 15 calories per hour, the calculation of the active time and sleep time during the day can be used in real-time linked with the body structure of the living user.

The input data as described above is processed in the calculation of the target amount of calories provides real-time body information consisting of the increase in consumption and consumption of aerobic exercise.

By carrying information on diet, it is possible to analyze real-time amount of exercise information, additional exercise amount and calorie intake, and operate as a continuous body manager. In addition, a program for weight control is available, which is useful for weight design and body care. By providing a food menu for diet to solve choices and concerns, and displays the current body calories are provided with a guide function that suggests the type and information of exercise. It is provided with basic data such as gata biorhythms and menstrual cycles, and simple calculations can be performed using a calculator. In particular, it is possible to consult with others through the use of database-based data, which can be helpful for maps and directions. Private information is guaranteed and diet information can be shared by exchanging information with each other. The function of monitoring the physical quantity of exercise is to calculate the calories burned for each user by performing calculation suitable for the user's constitution according to the interval and the degree of impact. In particular, the user can monitor the progress at any time to effectively practice the diet.

According to the portable diet manager according to the present invention as described above, by measuring the amount of exercise continuously in real time by the built-in shock sensor and adjust the degree of impact according to weight, constitution, sex, etc., it is possible to detect the exact movement It is easy to carry because it is not directional and can be used semi-permanently because it is electronic, and it continuously updates the food menu, exercise type and information for diet through the external interface, and monitors the progress at any time by calories. By displaying, it is effective to enable effective weight control, and the sound source is built into the ROM, which makes it suitable for brain and exercise at bedtime.
