ES2288125A1 - Automatic device of firing and deactivation for portable readers of bar codes and similar, has accelerometer, processor, unit of storage of pattern of accelerations and monitoring processor for monitoring accelerations - Google Patents

Abstract

The device has an accelerometer, a processor and a unit of storage of a pattern of accelerations. A monitoring processor for monitoring accelerations gathered by the accelerometer is provided. An order of firing is generated of the reader and disconnection of the reader takes place automatically when processor detects reading timing.

Description

Automatic trigger device and deactivation for portable barcode readers and Similar.

Object of the invention

The present invention relates to a automatic trigger and deactivation device for readers portable barcodes and the like.

Background of the invention

Code readers are currently used of bars or other optical reading devices (laser scanners, CCD or artificial vision) laptops, that is, they are handled with the hand, and for reasons of ergonomics incorporate power battery operated, allowing them total freedom of movement by not be connected by cables with any location permanent.

For reasons of battery conservation it is done  it is necessary to control its consumption, so that the reader activate only when the user wishes to perform a reading, staying off the rest of the time.

For this purpose manufacturers have developed various activation methods, including the trigger type "gun", and the proximity sensor that turns on the reader if a bar code to read is presented to it.

However, the trigger system presents the drawback that it is necessary to use a hand to grip the reader and trigger the trigger, so it is not a system "hands-free" and this is a limitation for certain uses for example in those where it is necessary to handle a hand lump simultaneously with code reading bars.

The proximity reader, on the other hand, produces  numerous spurious shots, because when moving the user passes the Scanner in front of the surrounding objects, causing with this unnecessary activations of the reader.

These inconveniences are corrected with the use of the device of the invention.

Description of the invention

The device of the invention serves as a Optimal way for automatic activation and deactivation of a optical reader such as a barcode reader, enabling Free use with your hands and minimizing failed shots.

According to the invention the device It comprises an accelerometer that measures, in real time, the accelerations that the team experiences in the X, Y and Z axes, a processor and a storage unit of a pattern of accelerations

The processor is programmed to monitor the accelerations collected by the accelerometer and compare them with the stored pattern, generating a trigger or activation order of the reader in case of coincidence.

The processor is also prepared to detect when the reading was made, then producing Automatically deactivate the reader. The device too integrates a timer, which usually runs on its own processor, which also automatically disconnects the reader if the reading has not been done once a preset timing. For the detection of the reading, the processor will implement a proper connection with any reader element that can provide you with this information, even the processor can integrate other functions of its own reader.

The acceleration pattern on the other hand is configurable by software, allowing training for different reading actions or for tuning the detection according to the user's particular gesture.

The elements that make up the device are integrated into the body housing of the reader, and mainly the accelerometer, which is what will detect the accelerations suffered By himself.

Brief description of the drawings

Figure 1 schematically shows the device of the invention.

Description of a practical embodiment of the invention

The device 1 of the invention comprises a accelerometer 2 that constantly measures accelerations in the X, Y and Z axes, a processor 3 and a storage unit 4 of a pattern of accelerations, so that the device is programmed for the processor to monitor accelerations collected by the accelerometer and compare them to the pattern stored in unit 4. In case of coincidence the processor generates a firing order of the optical reader 5 in which install the device, through a terminal 6 that, where appropriate can be adapted by means of a stage or buffer 7. Once done activation the processor is ready to detect that the reader or scanner has read to cause its disconnection It also performs a timing from the moment of activation, and causes the reader to disconnect if I have not the reading has elapsed after the set timing. Obviously the disconnection will also take place preferably at via connection 6.

As for stored acceleration pattern, can be defined and perfected through training thanks to the use of appropriate software tools, for which they will implement the appropriate interfaces, not represented.

The device, as seen in the figure, is integrated into the manageable housing 8 of the reader.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
