A wireless ad hoc pico network is formed by eyewear having a radio frequency transceiver and other devices such as a computer, a bracelet and a telephone having similar transceivers mounted on them. Master slave relationships are configurable. Other devices, such as a radio, a CD player, a hand held global positioning satellite system and a heart rate monitor, having similar transceivers, can also be connected with the transceiver of the eyewear. The transceivers operate on a globally available, unlicensed radio band of 2.45 gigahertz (GHz).
摘要:
A wireless ad hoc pico network is formed by eyewear and other devices such as a computer, a bracelet and a telephone having similar transceivers mounted on them. Master slave relationships are configurable. Other devices, such as a radio, a CD player, a hand held global positioning satellite system and a heart rate monitor, having similar transceivers, can also be connected with the transceiver of the eyewear. The transceivers operate on globally available, unlicensed radio band, 2.45 gigahertz (GHz) and conforms to the Bluetooth standard. The power consumption of Bluetooth enabled devices is less than three percent of the power consumption of a mobile phone. The eyewear includes a frame and connected to the frame are two temples. Temples are connected to frame via hinges. Temples have a male portion of a connector incorporated in them. Female portion of the connector is made integral with the hinges. When the male portion is inserted in the female portion the temple is attached to the frame. The temples can be removed by pulling the connector apart, and a temple with different apparatus within it can be inserted in place of the removed temples. The temple may have co-molded within its body, an apparatus such as an audio device, a camera, a speaker, and a microphone, and a display device such as liquid crystal or an alarm. In another embodiment, eyewear constitutes a distance alarm to monitor the movement of, for example, a child. A device in form of, for example, a bracelet is worn by the child. The transceivers in the eyewear and the bracelet form a small-range wireless network, i.e., piconet, wherein the eyewear and the bracelet communicate using signals conforming to the Bluetooth technology. The transceiver in the eyewear is configured to generate an alarm when the bracelet exceeds a predetermined distance from eyewear.

Systems and methods are provided for electroforming a dome for use in a dome switch. A mandrel having several dome shapes incorporated in a planar surface is provided. The mandrel can serve as a cathode in an electroforming process to construct a sheet of domes, for example by enabling the deposition of a sheet of nickel on the mandrel. The domes can be singulated from the sheet for use as part of dome switches. The electroforming process may ensure that the domes have a uniform thickness and no internal stresses that may affect the performance of the domes.

A cooling system, the system comprises a housing having an inlet and an outlet, a liquid to be flown from the inlet into the housing and out of outlet to exit the housing. The housing further has an interior portion for an electronic device to reside therein and a vibration transducer coupling to the housing. The liquid is flown across the electronic device to dissipate heat from the electronic device. The vibration transducer causes turbulent or agitation in the liquid as the liquid is flown across the electronic device.

A self-leveling plumb, level and pointing tool uses a visible laser diode to project light beams in two modes through two windows. Accurate, low cost structures for generating level and plumb beams and planes of light are disclosed. In principal embodiments, all leveling is accomplished using a very flexible coil spring as a pendulum element, a chain link connection in combination with such a spring, or a point contact suspension. Several accessories are disclosed for use with the laser tool. One accessory is a beam deviation accessory which can be used with the self-leveling laser tool to project a beam of known inclination. The accessory uses a pair of lenses whose relative positions are shifted to generate the desired angle.

An automatic plumb, level and pointing tool uses a visible laser diode to project light beams in two modes through two windows. In the first mode of operation, the unit is able to project a plumb-up beam and a level beam of light while resting on a surface which is as much as five degrees out of level. In the second mode of operation the unit is able to project two orthogonal beams of light both approximately in the horizontal plane for aligning one or more reference lines. An accurate, low cost method of generating level and plumb beams and planes of light is disclosed. One method uses an approximately leveled platform combined with a weak optical correction. The approximate leveling is done using a single wire or coil spring pendulum element which allows the platform to level itself to within a small fraction of true level, and remaining correction is provided by a weak negative lens or a weak reverse telescope. In alternative embodiments, all leveling is accomplished using a very flexible coil spring as a pendulum element, or a chain link connection in combination with such a spring. Several accessories are disclosed for use with the laser tool.

A system which is preferably employed in a laser alignment instrument produces up to five orthogonal beams from a single laser diode beam. The optics take advantage of the elliptical shape of the beam from a laser diode to produce a plurality of masked, parallel collimated beams which are then reflected by combinations of 45.degree.-angled and 90.degree.-angled mirrors, some fully reflective and some partially transmissive, to produce the orthogonal beams.

An automatic plumb, level and pointing tool uses a visible laser diode to project light beams in two modes through two windows. In the first mode of operation, the unit is able to project a plumb-up beam and a level beam of light while resting on a surface which is as much as 5.degree. out of level. In the second mode of operation the unit is able to project two orthogonal beams or light both approximately in the horizontal plane for aligning one or more reference lines. Accurate, low cost methods of generating level and plumb beams and planes of light are disclosed. One method uses an approximately or partially leveled platform combined with a refractive correction as a second stage. The approximate or partial leveling is done using a single wire, a coil spring or a ball-bearing gimbal pendulum element which allows the platform to partially correct for the out of level conditions, and remaining correction is provided by a weak negative lens, a weak reverse telescope or optical refraction at a liquid/air interface. An accessory is disclosed for use with the laser tool.
