DETAILED DESCRIPTION
It will be readily understood that the components of various embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of apparatuses of the present invention, as represented in the attached figures, is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention.
The features, structures, or characteristics of the invention described throughout this specification may be combined in any suitable manner in one or more embodiments. For example, reference throughout this specification to “certain embodiments,” “some embodiments,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in certain embodiments,” “in some embodiment,” “in other embodiments,” or similar language throughout this specification do not necessarily all refer to the same group of embodiments and the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Certain embodiments of the present invention provide a timer or counter that is securable to a contact lens case cap. Such a configuration has potential benefits over the art. For instance, such a timer is not limited to a single contact lens case, and can be moved to a new case if the other cap for the current case is lost or the case becomes dirty or marked. Also, a timer can be manufactured such that it is easily securable to contact lens caps of varying sizes. Accordingly, many embodiments of the present invention enjoy significant advantages over the art.
FIG. 1 is a top view of a contact lens case 100 with a timer 110 secured to the left contact lens case cap, according to an embodiment of the present invention. In some embodiments, a manual counter is used in lieu of a timer. The contact lens case includes a base 130, a left contact lens case cap (obscured from view by timer 110 and securing mechanism 140), a right contact lens case cap 120, a timer 110, and a securing mechanism 140. Timer 110 is shown secured to the left contact lens case cap in this embodiment, but timer 110 could also be secured to right contact lens case cap 120. Also, while only one timer is shown in this embodiment, a person of ordinary skill in the art will recognize that it is possible to secure a second timer to right contact lens case cap 120. Such a configuration would allow tracking of the left and right contact lenses separately in case one has been lost or damaged and replaced at a different time, or the left and right contact lenses have different times until needing to be replaced, assuming that timer 110 only has functionality for tracking one time period.
Timer 110 is secured around the left contact lens case cap, but does not interfere with the left contact lens case cap attaching to base 130. Timer 110 has a digital display 112 and a reset button 114. Digital counter 112 can either count up or count down to the number of days remaining in the lifetime of the contact lenses, depending on design choice, and digital display 112 may take any shape. The number of days may be fixed or adjustable by the user (for instance, options of 14 days, 30 days, 60 days, etc. may be provided). Also, while days are shown in this embodiment, hours, minutes, seconds, and/or any other time period or combination of time periods may be shown on digital display 112. In some embodiments, digital display 112 may provide separate counters for both the left and right contact lenses.
Reset button 114 resets the value of digital display 112 to a predetermined or user-selected value. Other buttons may also be present to facilitate selecting different timer values, setting an alarm that goes off when the time period expires, etc. In embodiments where alarm functionality is provided, speakers would also generally be present in timer 110, although a separate and/or remote speaker setup is possible, where the speakers are either hard-wired or remotely accessible by, for example, a radio signal or any other carrier means. While a digital display is provided in this embodiment, a non-digital counter that a user physically manipulates is also possible in addition to, or in lieu of, digital display 112. Such a non-digital counter could be, for instance, a wheel with numbers corresponding to days of remaining contact lens lifetime (see, for example, FIG. 11).
In this embodiment, securing mechanism 140 completely envelops timer 110, save for an opening for digital display 112 and reset button 114. Securing mechanism 140 may also envelop the back of timer 110, sitting between timer 110 and the left contact lens case cap. Securing mechanism 140 may be manufactured from rubber, plastic, cloth, or any other material suitable material. In some embodiments, rubber may be preferable due to its elasticity. Securing mechanism 140 may be attached to timer 110 or may simply slide over timer 110 and hold timer 110 in place against the contact lens case cap. Such a securing mechanism may enable timer 110 to be secured to contact lens case caps of varying sizes, reducing or eliminating the need to manufacture multiple sizes. This feature may allow such embodiments to be manufactured more cost effectively.
FIG. 2 is a top view of a contact lens case 200 with a timer 210 secured to the left contact lens cap, according to an embodiment of the present invention. In some embodiments, contact lens case 200 may be the same as contact lens case 100 of FIG. 1. The contact lens case includes a base 230, a left contact lens case cap (obscured from view by timer 210 and securing mechanism 240), a right contact lens case cap 220, a timer 210, and a securing mechanism 240. Timer 210 is secured around the left contact lens case cap, but does not interfere with the left contact lens case cap attaching to base 230. Timer 210 has a digital display 212, a reset button 214, and a speaker 216. Reset button 114 resets the value of digital display 112 to a predetermined or user-selected value. Speaker 216 permits the generation of sounds including, for example, acknowledgement beeps when a user presses the reset button and generating an alarm then the lifetime of the contact lenses expires.
In this embodiment, securing mechanism 240 completely envelops timer 210, save for an opening for digital display 212, reset button 214 and speaker 216. Securing mechanism 240 includes gaps 242 around the periphery of securing mechanism 240. Such gaps may allow the material of securing mechanism to flex more easily in order to be securable to a contact lens case cap.

Holding pin 1112 may be a pin, bolt, or any other suitable means for facilitating the rotation of manual counter 1110. An arrow 1114 designates the current day on manual counter 1110. In this embodiment, securing mechanism 1140 envelops manual counter 1110, except for an opening for the display face of manual counter 1110.
In many embodiments, the operation of the timer is implemented by a digital controller. FIG. 12 illustrates a controller 1200, according to some embodiments of the present invention. Controller 1200 includes a bus 1205 or other communication mechanism for communicating information, and a processor 1210 coupled to bus 1205 for processing information. Processor 1210 may be any type of general or specific purpose processor, including a central processing unit (“CPU”) or application specific integrated circuit (“ASIC”). Controller 1200 further includes a memory 1215 for storing information and instructions to be executed by processor 1210. Memory 1215 can be comprised of any combination of random access memory (“RAM”), read only memory (“ROM”), flash memory, cache, static storage such as a magnetic or optical disk, or any other types of computer-readable media or combination thereof. Additionally, controller 1200 includes a communication device 1220, such as a wireless network interface card, to provide wireless access to a network. However, such a communication device adds cost and may not be desired for many models, so it is not present in many embodiments.
Computer-readable media may be any available media that can be accessed by processor 1210 and may include both volatile and non-volatile media, removable and non-removable media, and communication media. Communication media may include computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media.
Processor 1210 is further coupled via bus 1205 to a display 1225, such as a Liquid Crystal Display (“LCD”), for displaying information, such as timing information, to a user. A first button 1230 and a second button 1235 are further coupled to bus 1205 to enable a user to interact with controller 1200.
In one embodiment, memory 1215 stores software modules that provide functionality when executed by processor 1210. The modules include a timer module 1240 that provides timing functionality for controller 1200. The modules further include an alarm module 1245 that is configured to facilitate an alarm when the timer expires. Controller 1200 may include one or more additional functional modules 1250 to include additional functionality.
Presenting the above-described functions as being performed by a “controller” is not intended to limit the scope of the present invention in any way, but is intended to provide one example of many embodiments of the present invention. Indeed, apparatuses disclosed herein may be implemented in localized and distributed forms consistent with computing technology.
It should be noted that some of the controller features described in this specification have been presented as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom very large scale integration (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, graphics processing units, or the like.
A module may also be at least partially implemented in software for execution by various types of processors. An identified unit of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions that may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module. Further, modules may be stored on a computer-readable medium, which may be, for instance, a hard disk drive, flash device, random access memory (RAM), tape, or any other such medium used to store data.
Indeed, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
Some embodiments of the present invention provide a timer or counter that is securable to a contact lens case cap. The timer or counter may be secured by a securing mechanism that envelops the timer or counter, a strap, a post member with a strap, magnets, adhesives, or any other suitable mechanism. Such a timer or counter may be attached to contact lens cases of varying sizes and has a utility and portability that other timers and counters in the art lack.
It should be noted that reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment of the invention. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, discussion of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment.
Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize that the invention can be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.
One having ordinary skill in the art will readily understand that the invention as discussed above may be practiced with steps in a different order, and/or with hardware elements in configurations which are different than those which are disclosed. Therefore, although the invention has been described based upon these preferred embodiments, it would be apparent to those of skill in the art that certain modifications, variations, and alternative constructions would be apparent, while remaining within the spirit and scope of the invention. In order to determine the metes and bounds of the invention, therefore, reference should be made to the appended claims.
