摘要:
An electronic device (100) having a multi-mode acoustic system (120) and a method (500) for radiating sound waves are described herein. The acoustic system (120) generally includes a transducer (530), a first port (510), and a second port (520). The first and second ports (510, 520) may be acoustically coupled to the transducer (530). The second port (520) may be acoustically symmetric relative to the first port (510) such that output from the second port (520) is substantially identical to output from the first port (510).

A semitransparent display (100), suitable for use with an electronic device (700), is provided. The semitransparent display (100), in one embodiment, includes a cholesteric liquid crystal display layer (101) and a translucent electroluminescent layer (102), such as an organic light emitting diode device. Control circuitry (109) is coupled to each layer, and is configured to selectively actuate each layer. The cholesteric liquid crystal display layer (101) can be operated in any of a planar mode (201), a focal conic mode (202), or a homeotropic mode (203). Segments of the cholesteric liquid crystal display layer (101) can be selectively actuated so as to hide and reveal user actuation targets. Capacitive sensors (620, 621) can be included so that the semitransparent display (100) works as a touch sensitive user interface. A user can see an object, such as a hand (105) or stylus, from above the semitransparent display (100) when the hand (105) or stylus is placed beneath the semitransparent display (100).

摘要:
A speakerphone accessory (100) is provided for use with a portable telephone (102). The speakerphone accessory (100) has a high-level speaker assembly (222) that includes a transducer (500) coupled to first and second resonators (502, 504). The first and second resonators (502, 504) are designed so that the first resonator (502) is most efficient at a high frequency while the second resonator (504) has maximum response at a low frequency. The frequency ranges produced by the first and second resonators (502, 504) overlap to reproduce frequencies between the high and low frequencies. The high-level speaker assembly (222), therefore, provides an acoustic bandpass having improved response when compared to the response of the transducer (500) alone. In addition, the speakerphone accessory (100) has a housing (130) and porting structure which allows the accessory (100) and attached portable telephone (102) to be used in a variety of positions without obstructing sound generated by the high-level speaker assembly (222).

A compact input device (104), suitable for entering data in an electronic device (102), includes a cylindrical surface (202) that has a keyboard switch matrix (210) deployed on the outer body of the cylindrical surface (202) formed by a first extendable interlocking part (412) and a second extendable interlocking part (414). The first extendable interlocking part (412) includes a left half of a QWERTY keyboard (e.g., Q, W, E, R, T) while the second extendable interlocking part (414) includes a right half of a QWERTY keyboard (e.g., Y, U, I, O, P). When the compact input device (104) is in an extended and aligned configuration, the keys of the first extendable interlocking part (412) and the keys of the second extendable interlocking part (414) form a common QWERTY keyboard configuration.
摘要:
In a method of controlling power level of transmit signals from a wireless communication device that is communicating with a plurality of wireless ad-hoc network nodes as part of an ad-hoc network, a value of a usage parameter of a communication between the wireless device and a first wireless ad-hoc network node of the plurality of nodes is detected. A power level of a transmit signal from the wireless device to the first wireless ad-hoc network node is set to a level corresponding to the value of the usage parameter. A device for adjusting a power level in a wireless device includes a parameter detection circuit, that detects a parameter indicative of a relationship between the wireless device and a wireless ad-hoc network node, and a power selection circuit that sets a transmit signal power level from the wireless device to a level corresponding to the parameter detected by the parameter detection circuit.
