Therefore, the calculation unit (not shown) of the measuring instrument 200 may use the measured values of the sensor array 230 of FIG. 4 and the infrared sensor unit 240 of FIG. 5, the green speed, the friction coefficient of the putting mat 100, etc. Information to be displayed on the display 260 may be calculated based on the information, and the result of the calculation may be controlled to be output to corresponding display units.

As used herein, the term “unit” (eg, a controller) may refer to a unit including one or a combination of two or more of, for example, hardware, software, or firmware. “Unit” may be used interchangeably with terms such as, for example, unit, logic, logical block, component, or circuit. A "unit" may be a minimum unit of an integrally constituted part or a part thereof. A “unit” may be a minimal unit or part thereof that performs one or more functions. A “unit” may be implemented mechanically or electronically. For example, a "part" is an application-specific integrated circuit (ASIC) chip, field-programmable gate arrays (FPGAs), or programmable-logic device that performs certain operations, known or developed in the future. may contain at least one.

A module or program module according to various embodiments may include at least one or more of the aforementioned elements, some may be omitted, or additional elements may be further included. Operations performed by modules, program modules, or other components according to various embodiments may be executed in a sequential, parallel, repetitive, or heuristic manner. Also, some actions may be performed in a different order, omitted, or other actions may be added.

As used herein, the term "a" is defined as one or more than one. Also, the use of introductory phrases such as “at least one” and “one or more” in a claim means that the same claim includes introductory phrases such as “at least one” and “one or more” and ambiguous phrases such as “an”. If any, be construed to mean that the introduction of another claim element by the ambiguous phrase "an" limits any particular claim containing the so-introduced claim element to an invention containing only one such element. It shouldn't be.

In this document, expressions such as "A or B" or "at least one of A and/or B" may include all possible combinations of the items listed together.

Unless otherwise specified, terms such as "first" and "second" are used to arbitrarily distinguish the elements they describe. Thus, these terms are not necessarily intended to indicate a temporal or other order of priority of such elements, and the mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage. . Accordingly, these terms are not necessarily intended to indicate a temporal or other priority of such elements. The mere fact that certain measures are cited in different claims does not indicate that a combination of these measures cannot be useful.

In addition, terms such as "front", "back", "top", "top", "bottom", "bottom", "above", "below" in the detailed description and claims are used for descriptive purposes, but It is not necessarily used to describe permanent relative positions. It is understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein may, for example, operate in directions other than those shown herein or otherwise described.

It will be understood that for the sake of illustrative simplicity and clarity, elements (elements) shown in the figures are not necessarily drawn to scale. For example, the dimensions of some elements may be exaggerated relative to others for clarity. Also, where considered appropriate, reference numbers may be repeated between the drawings to indicate corresponding or like elements.

Arrangements of components to achieve the same function are effectively "related" so that the desired function is achieved. Thus, any two components that are combined to achieve a particular functionality may be considered "related" to each other such that the desired function is achieved, regardless of structure or intervening components. Similarly, two components so associated can be considered "operably connected" or "operably coupled" to each other to achieve a desired function.

The phrase “may be X” indicates that condition X can be met. This phrase also indicates that condition X may not be met. For example, a reference to a system that contains a specific component should also include a scenario where the system does not contain that specific component. For example, a reference to a method that includes a specific action must also include scenarios in which the method does not include that specific component. But to take another example, a reference to a system configured to perform a specific action should also include a scenario in which the system is not configured to perform the specific action.

The terms "comprising", "having", "consisting of", "consisting of" and "consisting essentially of" are used interchangeably. For example, any method may include at least the operations included in the drawings and/or specifications, and may include only the operations included in the drawings and/or specifications. Alternatively, the word "comprising" does not exclude the presence of the recited elements or acts in a claim.

In one embodiment, the illustrated examples may be implemented on a single integrated circuit or as circuitry located within the same device. Alternatively, the above examples may be implemented as any number of discrete integrated circuits or discrete devices interconnected with each other in any suitable manner, and other alterations, modifications, variations and alternatives are also possible. Accordingly, the specification and drawings are to be regarded in an illustrative rather than restrictive sense.

Also, for example, any of the foregoing examples or portions thereof may be implemented as a software or code representation of a physical circuit or a logical representation translatable to a physical circuit, such as any suitable type of hardware description language.

A system, apparatus or device referred to in this specification includes at least one hardware component.

In the above, a preferred embodiment of the technology of this specification has been described with reference to the accompanying drawings. Here, terms or words used in this specification and claims should not be construed as being limited to ordinary or dictionary meanings, but should be interpreted as meanings and concepts consistent with the technical spirit of the present invention. The scope of the present invention is not limited to the embodiments disclosed herein, and the present invention can be modified, changed, or improved in various forms within the spirit of the present invention and the scope described in the claims.
