FIELD OF THE INVENTION
The present invention relates generally to glasses and, more particularly, to a pair of eyeglasses with a clock or other electrical component.
BACKGROUND OF THE INVENTION
For some people, glasses are indispensable. They have to wear them almost every second of their waking hours. Even for those who do not wear prescription glasses, if they like to be in the sun, sunglasses are essential. In other words, many of us constantly carry at least one pair of glasses with us.
Many of us also have to regularly wear or carry a watch or other electrical devices. Some people are already burdened by carrying too many separate devices and it can be expensive and inconvenient when a device is lost or forgotten.
Another interesting aspect in the glasses industry is that once you have bought a pair of glasses, they cannot be altered. Some of these glasses can be quite expensive, particularly those with a famous brand name. After-market enhancements or modifications to a pair of glasses are not readily available.
It should also be apparent from the foregoing that there is a continuing need to reduce the number of separate components or gadgets one tends to carry, and there is also a need to facilitate after-market enhancements or modifications for a pair of glasses.
SUMMARY OF THE INVENTION
In one embodiment, the present invention relates to having a clock at least partially embedded in a pair of glasses. With the clock at least partially embedded in the glasses, the wearer does not need to carry a separate watch in order to know what time it is. For example, the clock can be in one of the temples of the glasses at a region close to the hinge of that temple, with the clock facing the wearer. With the clock in that position, the wearer may be able to see the time or the time may be visible to the wearer, without the need to take the glasses off. In an alternative example, the clock, which can be a digital clock, can be in a temple arrangement of a pair of glasses. A temple arrangement can be a temple tip, a temple cover or a temple fit-over. In another embodiment, instead of a clock, the present invention relates to an electrical component at least partially embedded into a pair of glasses or a temple arrangement of a pair of glasses. Due to the miniaturization of electrical components, even a physically small electrical component can provide significant and useful functionalities. In one example, an electrical component in a pair of glasses is a temperature sensor. In another example, an electrical component in a pair of glasses is an RFID tag. In still another example, an electrical component in a pair of glasses is an eyewear finder.
Other aspects and advantages of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the accompanying drawings, illustrates by way of example the principles of the invention.

However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments.
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a pair of glasses according to one embodiment of the present invention. The pair of glasses 10 has a first lens holder 12 and a second lens holder 14. Both lens holders 12, 14 are for receiving lenses. The first lens holder 12 has a first side and a second side. The second lens holder 14 also has a first side and a second side. The pair of glasses has a bridge element 16. The bridge element 16 is coupled to the first side of the first lens holder 12 and the second side of the second lens holder 14. In one embodiment, the lens holders and the bridge element 16 are not separate pieces, but are an integral piece.
The pair of glasses 10 also includes a first temple 16 and a second temple 18. The first temple 16 is pivotally secured to the second side of the first lens holder 12 through a joint or hinge 20. The second temple 18 is pivotally secured to the first side of the second lens holder 14 through another joint or hinge 22.
The glasses 10 shown in FIG. 1 also include a clock 24, which is at least partially embedded in the glasses 10. In one embodiment, the clock 24 can be in the temple 18 of the glasses 10 at a region close to its corresponding joint 22. The clock 24 is facing a user when the user is wearing the glasses. With the clock in that position, in some implementations, the wearer is able to see the time without the need to take the glasses off.
The clock 24 can be a digital clock (or a digital alarm clock) with a liquid crystal display (LCD) or other types of electronic display. In another example, the clock is an analog clock, or other type of clock.
The glasses 10 can also include a switch 26 that can be used to adjust the time of the clock 24. The switch 26 can be a push button, or a knob that one can adjust or rotate, similar to the knob in an analog watch. Different types of switches are applicable. In one embodiment, the clock 24 is a digital clock and the switch 26 is an electrical switch. Different types of switches have previously been described in the related patent applications mentioned above and incorporated by reference.
A battery 30 can also be provided in the glasses 10 to power the clock 24. In one embodiment, the glasses 10 include a hatch that can be opened to replace the battery 30. The hatch can be facing the wearer when the glasses 10 are worn. In another embodiment, the glasses 10 do not include a hatch for facilitating changing of the battery. In this embodiment, the glasses are designed so that once the power in the battery is depleted, the battery cannot be replaced without breaking the glasses. In still another embodiment, the battery can be rechargeable by way of coupling to a charger or by way of a solar cell coupled to or partially embedded in the glasses.
In the embodiment, where the clock is a digital clock, the clock can be programmable.
In one embodiment, the clock is an alarm clock, and there is also a speaker at least partially embedded in the glasses 10. As an example, the speaker can be a beeper. In another embodiment, the alarm clock can be programmable to audibly alert a user at a specific time using an audible output from the speaker. In the various related patent applications mentioned above and incorporated by reference, many ways to at least partially embed a speaker into a temple are described.
In another embodiment, the clock is a digital clock with a display. The glasses can further include a switch that turns the display on and off. Sometimes, the wearer may not want to be reminded of time. In this embodiment, the clock itself can be turned off. In another embodiment, the clock is a digital clock with a LCD and an electrical switch. The electrical switch can turn off the LCD, while the clock is still running or is still continuously operating.
In one embodiment, there is a slidable lid (or cover) over the face of the clock. One can slide the lid to cover the face of the clock.
In one embodiment, the clock displays only the time of day. In another embodiment, the clock displays not only time, but also the date and the day of week. The size of the display can be smaller if only the time of day is displayed. The time, date and day can be displayed simultaneously. Alternatively, the display can cycle through displaying time, date, and day, thereby providing a sequential display of such information.
In yet another embodiment, a housing for the clock includes a light source next to the clock to help the wearer see the time. For example, a light emitting diode can be provided next to the clock, and the light emitting diode can be turned on/off. In yet another embodiment, there is a cavity in the glasses and the clock is a self-contained clock with its own battery, i.e., a clock module. The clock module is placed in the cavity. A cavity is then closed and sealed to keep the clock module inside the glasses. The clock can be a digital clock and the digital clock may only display the time of day. In one embodiment, the clock can also set its time, date and/or day by a wireless signal. For example, the clock can include a wireless receiver to acquire the wireless signal. The wireless signal can be acquired from a network, such as a WiFi or Cellular network. The wireless signal can also be acquired from a broadcast. For example, the NIST radio station WWVB broadcasts signals that can be used to synchronize consumer electronic products, like clocks.
In the embodiment shown in FIG. 1, the clock faces inside, towards the wearer when the glasses are being worn. Alternatively, the clock could be facing out and the user can temporarily remove the glasses to read the time.
A clock can be based on separate light sources. In one embodiment, the clock display is at least partially embedded in the lens holders of a pair of glasses. There can be twelve (12) light sources located all around each lens holder. The light sources could be LEDs or LCDs. The light sources around the left lens holder can show the hour, and the light sources around the right lens holder can show the minutes, which can be rounded to the nearest five minutes. As another example, the light sources can be around one of the lens holders, with different colors or other visual clues used to distinguish hours and minutes. There can be a switch provided with the pair of glasses to temporarily activate the display. For example, the switch can be located at the bridge or temple of the glasses. In one embodiment, the lens holders can be made of translucent materials.
In one embodiment, a clock can be in a temple arrangement of the glasses.
Referring back to FIG. 1, each temple has two ends, the first end and the second end. The first end is the end that is pivotally secured to its corresponding hinge. In one embodiment, the second end of one or both temples has a temple arrangement.
For some glasses, particularly when a pair of glasses has not been extensively worn, a temple arrangement, such as a temple tip, can be relatively easily removed and re-inserted into the glasses. As result, temple arrangements of different color and/or shape and/or having different electrical components can be applied to the same frame of a pair of glasses. Retailers or distributors can then provide after-market modification or enhancement to a pair of glasses, at the preference of their consumers. This, for example, can be done by replacing existing temple tips with replacement temple tips. Or, a consumer can identify the preferred temple arrangements to be sold with the glasses. Different embodiments on after-market enhancement and/or modification of glasses have previously been described in the related patent applications mentioned above and incorporated by reference.
FIG. 2 shows a number of different embodiments of temple arrangements according to the present invention. For example, a temple arrangement can be a temple tip, which is usually associated with a rearward position of the temple.
In another embodiment, a temple arrangement is a temple cover, or a temple fit-over. A temple cover slides over and at least partially covers a portion of the second end of a temple. If the second end of the temple has a temple tip, at least a portion of the temple tip can be covered by the temple cover. A temple fit-over fits over at least a portion of the second end of a temple. If the second end of the temple has a temple tip, at least a portion of the temple tip is fitted over by the temple fit-over. A temple cover is typically made of a material that is more flexible than a temple fit-over. For example, a temple cover can be a fabric or other materials, such as a sock or sleeve; while a temple fit-over can be made of plastic.
A temple arrangement can be made of the same or different materials than the temple. To illustrate, a pair of glasses with a metal frame can have non-metallic temple tips. A temple arrangement can be of a color that is the same as, or similar to, or different from, that of the temple.
A temple arrangement can be held onto a temple by frictional force. If the temple arrangement is a temple fit-over, it can be held onto a temple tip by frictional force. In another embodiment, a temple arrangement is permanently held onto its corresponding temple or temple tip. This can be done by adhesive or glue.
In different embodiments, the glasses 10 can be, for example, a pair of sunglasses, fit-over glasses, reading glasses, prescription glasses, or safety glasses. In other embodiments, the glasses 10 can be, for example, a pair of sports glasses, protective goggle, ski goggle or swimming goggle. In a further embodiment, one or more electrical components can be in a strap tied to the corresponding eyewear, such as a sports strap tied to the corresponding sports eyewear.
In a number of embodiments, the temples of the glasses can have a tapered profile. Each of the temples is wider or broader when it is close to its corresponding joint. In one embodiment, a wider or broader temple implies that the temple spans across a wider or broader area longitudinally down from the top of the head of the user.
Depending on applications, a temple arrangement can be of different shapes. The shape can depend on the type of glasses. For example, the temple arrangement for fit-over glasses can be bigger than that of the prescription glasses. The shape can also depend on applications based on the electrical component(s) embedded or partially embedded in the glasses.
In one embodiment, the glasses include lenses. The glasses, such as the lens holders with the corresponding lenses, can use a wrap around style to better conform to the profile of the face of the wearer.
In another embodiment, each lens holder also has a shield at least at one of its edges. The shield can reduce the amount of light or radiation entering, for example, between the lens holders and the wearer's head, and received by at least one of the eyes of the wearer. The shields can be shaped to conform to the profile of the face of the wearer. In an example for fit-over sunglasses, when worn over a pair of prescription glasses, such shields can go over or cover at least a portion of the pair of prescription glasses. The shields can be opaque. Optionally, there can be transparent or translucent windows on these shields.
Note that in one embodiment, a pair of glasses does not have to include lenses.
In one embodiment, one or more electrical components are at least partially or fully embedded in a temple arrangement. Such an embedded electrical component can be an electronic clock. FIG. 3 shows examples of different electrical components according to the present invention.
In one embodiment, an electrical component in a pair of glasses is an electrical connector. The connector can be provided on one of the temples of the pair of glasses. The connector can be a male connector located at a temple tip. In another embodiment, the connector can be a female connector at a temple tip. As that temple tip grabs onto the main body of its corresponding temple, the female connector can make electrical contact with a male connector. Different types of connectors have previously been described in the related patent applications, which have been incorporated by reference.
In one embodiment, an electrical component in a pair of glasses is an electrical switch, such as one or more of those previously described in the related patent applications, which have been incorporated by reference.
In one embodiment, an electrical component in a pair of glasses can include a circuit board. The circuit board can be a rigid or a flexible circuit board.
In one embodiment, an electrical component in a pair of glasses can be a power source. The power source can be a battery, a solar cell or other type of power source.
In one embodiment, an electrical component in a pair of glasses is a speaker. The speaker can be facing the wearer when the glasses are being worn. The speaker can directly transmit to a user, such as a speaker mounted on an exterior surface of an eyeglass frame, or partially or fully embedded in an eyeglass frame, or a bone-conducting speaker.
A bone-conducting speaker transfers vibrations from bones in one's head, such as cheekbone, to the inner ear through bone-conduction technology. One advantage of a bone-conducting speaker is that it does not need an ear bud sticking into one's ear, or additional wires to transmit sound. Such wires or ear bud can be inconvenient, such as when one is swimming. Different types of bone-conducting speakers have previously been described in the related patent applications, which have been incorporated by reference.
Alternatively, the speaker can indirectly transmit sound to a user, such as through the use of a tube to delivery audio signals proximate to a user's ear.
In one embodiment, an electrical component in a pair of glasses is a memory device and/or processing circuitry. The memory device is for data storage. The processing circuitry controls operation of data acquisition with respect to other electrical components and/or processing of data.
In one embodiment, an electrical component in a pair of glasses is a frequency receiver or a frequency transmitter. They can be in the radio frequency range.
In one embodiment, an electrical component in a pair of glasses can be a sensor. The sensor can be a temperature sensor. The temperature sensor can be used to sense the temperature of the wearer, which can be based on heat conduction. In one embodiment, such a temperature sensor is in a temple tip. In measuring the temperature, the user can further press the temple tip towards the head of the user to ensure better connection. One can also stick the temple tip under one's tongue to measure body temperature.
In other different embodiments, an electrical component in a pair of glasses can be a motion detector, a speed sensor, a rate of ascent detector, a pressure detector, or a detector for radiation, such as an ultraviolet (UV) sensor.
In one embodiment, an electrical component in a pair of glasses is a radio frequency identification (RFID) tags. RFID tags typically include memory chips equipped with radio antennas. The memory chips usually do not include large amount of information. They may only have a few kilobytes, sufficient to encode, such as a serial number, where and when the product, such as the glasses, was manufactured, and other relevant information. A portion of such information can provide identifying information to the glasses.
These tags can come in a number of configurations. For example, an active tag uses a battery-powered transponder to constantly emit signals, carrying information programmed into the chip. Active tags are more applicable to situations where readers are not close to the tags. A semi-passive tag likewise has a battery, but may not be activated until it receives a signal from a reader. They are more applicable to situations that do not need continuous connection and accessing. A passive tag has no battery; its antenna extracts power from the reader's radio wave signal to transmit the identifying information on the chip. Passive tags are typically relatively inexpensive, but may have to be within a few feet of a reader to extract power. The electrical component can be a passive RFID tag, or some other type of tag.
In one embodiment, one or more electrical components in a temple arrangement interact with one or more electrical components in another part of the glasses or in a device tethered to the glasses. For example, there can be two temperature sensors, one in a temple tip and the other close to the hinge of the corresponding temple. The sensor close to the hinge is used to identify the temperature of the environment, while the sensor at the temple tip is used to measure the temperature of the wearer. In one embodiment, based on the differential output from the two sensors, the temperature of the wearer can be identified. Based on the differential output from the two sensors, the effect of the environment temperature is taken into consideration in identifying the temperature of the wearer of the glasses.
In another example, a temple of a pair of glasses holds one portion of an electrical circuit. That portion can include generic parts, such as a battery or a solar cell, a display, a memory device, a beeper and/or a controller (or processor), which can be programmable. The one or more electrical components can be on a printed circuit board. They can be generic components applicable to many different types of operations.
In one embodiment, another portion of the electrical circuit is in a temple arrangement. This portion can be application specific. For example, the battery to run a clock is in a temple, while the digital clock without its battery is in the corresponding temple arrangement.
In another example, a temperature sensor is in a temple arrangement, while a switch, a display, a processor, a memory device and a battery are in the temple. There can also be a thermal mass in the temple arrangement. With the thermal mass, the temperature of the sensor would not change too quickly. With the switch in the on position, the processor can cause the sensor to measure temperature. The processor keeps track of the temperature of the sensor as it changes. The information can be stored in the memory device.
In another embodiment, the temperature sensing glasses also have a beeper in the temple. When the sensor temperature does not fluctuate by more than a certain threshold within a preset amount of time, the beeper can produce a beeping sound. This indicates that the temperature is now stable.
One way to use a temperature sensor in a temple of a pair of glasses is as follows. First, one turns the switch on. Assume the person pushes the sensor so that it touches the head at the back of the ear of the user, and the temperature of the sensor starts to go up. A processor or controller keeps track of the temperature of the sensor. If the temperature does not vary by more than, for example, 0.1 degree in, for example, 5 seconds, the temperature is assumed to be in equilibrium. The processor keeps on calculating running averages. Once the fluctuation is below the preset 0.1 degrees, the beeper beeps. After the beeper beeps, the sensor stops measuring temperature, and the last temperature taken by the sensor will correspond to the temperature of the wearer. The display then shows this last temperature. This process can be re-started by turning the switch off and on.
In other embodiments, a motion detector, a speed sensor for skiing, a rate of ascent detector for diving, a radiation detector (such as a UV sensor), or a pressure sensor can be in a temple arrangement. Each of these sensors or detectors can work in conjunction with other electrical components in the glasses. Different types of UV or radiation sensing embodiments have previously been described in the related patent applications, which have been incorporated by reference.
In one embodiment, the glasses include an active RFID tag. Different electrical components can be in different parts of the glasses. For example, the battery can be in the temple, and the transponder of the tag can be in the corresponding temple arrangement.
In one embodiment, the glasses include electrical components for locating the glasses. This is an embodiment of an eyewear finder. Sometimes we do not remember where we placed or misplaced the glasses. This embodiment helps us find the glasses.
FIG. 4 shows eyewear finder components according to different embodiments of the present invention. In one approach, the glasses include a semi-passive RFID tag, a battery and a speaker, such as a beeper. These components can be in the frames of the glasses. In another embodiment, some of its electrical components can be in the frame of the glasses, and some of its electrical components can be in a temple arrangement of the glasses. For example, its power source and beeper can be in one of its temples, and the tag in the corresponding temple arrangement. The tag is activated when it receives a specific signal from its reader or finder. The reader or finder can be a generator for specific RF signal. By pushing a button on the reader, the specific signal will be transmitted. When the tag gets the specific signal, the tag will activate the beeper, which will generate a beeping sound. As long as the user is within the hearing range of the beeping sound, the user will be able to find the pair of glasses.
In another approach for an eyewear finder, there is a RF receiver, an ultrasonic receiver or other types of receiver in the glasses, which can couple to a beeper. The receiver is designed to receive a specific signal. The finder can generate the corresponding signal, which can be RF or ultrasonic signals. When the receiver detects the transmitted signals, the receiver will generate a beeping sound, which can then help locate the position of the glasses. Typically, the finder is for short-range application, and can use technologies can be based on Zigbee, UWB, Bluetooth or WiFi standards.
Based on a number of embodiments described, retailers or distributors can provide after-market modification or enhancement to a pair of glasses. For example, this can be done by replacing existing temple tips with replacement temple tips of a pair of glasses.
A replacement temple arrangement can include different electrical components for different applications. Alternatively, the replacement temple arrangement can have similar electrical components, but is of different shape or color than the original one.
In another example, the distributors can have a whole range of temple arrangements in different colors and/or shapes and/or electrical components for a customer to select from. Once the customer has selected one, the distributor will insert that temple arrangements to the glasses and sell the glasses to the customer. The distributor can also permanently fix the temple arrangements to the glasses so that they cannot be removed from the glasses without distorting or breaking the glasses.
In yet another embodiment, the distributor can allow the customer the option of replacement temple arrangements after the customer has bought the pair of glasses (e.g., as long as the customer returns the glasses within a preset period of time). For example, the preset period of time is one week. The customer has the option to replace the temple arrangements bought with another set. If the prices are different, the customer will either get a refund or has to pay the extra amount.
Additional descriptions regarding temple arrangements have been disclosed in the related patent applications, which have been incorporated by reference.
In a number of embodiments, electrical components have been described to be fully or partially embedded in a temple of glasses, or in a temple arrangement. In other embodiments, the component(s) can be in other parts of the glasses, such as the lens holders, the nose pads, the bridges or the shields.
A number of embodiments have been described regarding glasses with a number of structural elements. In one embodiment, the glasses can utilize rimless frames. The glasses can include two lenses held together by a bridge. A temple can be attached to each lens through a joint that is connected to the corresponding lens by one or more screws. For example, there can be two screws at each lens to hold onto a temple piece, which includes a joint for a corresponding temple. One or more electrical components can be fully or partially embedded in the glasses, such as in a temple of the glasses.
In another embodiment, the electrical components, or at least some of the electrical components, in the glasses can be tethered to the glasses instead. A number of tethered embodiments have been described in related patent applications mentioned above and incorporated by reference.
In one embodiment, the electrical components can also pertain to an activity monitor, such as a pedometer. The activity monitor can be partially or completely embedded in a pair of eyeglasses. Typically, the activity monitor includes an activity sensor and electronic circuitry in the pair of eyeglasses that monitor the activity, process the monitored signals, and provide an output of an activity indication to the user or interested party. Additional details on activity monitors are described in related patent applications mentioned above and incorporated by reference
