Abstract: Methods and apparatus for configuring a portable communication device are disclosed. The methods include receiving an incoming audio signal, adjusting the incoming signal audio level based on a volume control setting, generating an ultrasonic audio signal having an audio level independent of the volume control setting, mixing the incoming signal with the ultrasonic signal to generate a mixed audio signal, outputting the mixed signal to a remote audio device, receiving a remote audio signal from the remote device, and comparing the remote signal audio level to one or more thresholds to determine whether to output a compensated audio signal to a speaker. The remote signal may be detected by the remote device in response to sound output from the remote device based on the mixed signal, and the compensated signal audio signal may be adjusted based on an estimated loss in loudness associated with the remote signal audio level.

Abstract: A method and personal stereo speaker system is provided for providing audio to a user. Speakers provide audio to the ears of a user. The speakers are preferably mounted on the shoulders of the user. The audio emanating from the speakers has a beam angle and an audio level. When the system detects that the head of the user has moved, either side-to-side, up and down, or rotationally, or that the user has commended moving, a controller changes at least one of the beam angle and the audio level in response to the movement. This improves the quality of the sound heard by the user and also keeps the privacy of the audio optimized.

Abstract: A coil-in-coil structure (100) is formed within two devices (106, 108). The coil-in-coil structure (100) enables both wireless charging and secure pairing between the two devices (106, 108). The coil-in-coil structure (100) permits expanded wireless functionality using a single transmit coil (104) at a host radio device (108) and a receive coil (102) at an accessory device (106). A plurality of different accessory devices (606) can be interchangeably accommodated via a single host port (114) of the radio device (108).

Abstract: An irrigating device and a deflector for even spraying of liquid across non-circular areas are presented. The irrigating device includes a base comprising at least a groove; a cap; and a deflector including at least a butterfly ridge, a groove, and a plurality of hydrodynamic ribs, wherein the butterfly ridge is structured with a continuous series of angles to allow equal quantity of liquid per distance on the radius and diagonal, wherein the groove is structured to allow full liquid coverage at a zero point, and wherein the plurality of hydrodynamic ribs are structured to control at least the irrigated distance.

Abstract: Upright and pendent sprinkler devices for spraying non-circular or semi non-circular areas are disclosed.

Abstract: A computer component heater is operably coupled to a pulse width modulation (PWM) power controller, the power controller is operable to automatically vary a duty cycle in relation to the voltage of the power source supplying the heater.

Abstract: A heat sink (100) includes a cooling block (105) having a plurality of fins (110) extending through the block to provide a series of coolant channels (112) extending between the fins, the channels having in the interior of the block a venturi narrowing. Beneficially, the channels have coolant entry regions in at least two different regions (115, 120) of the block to direct a plurality of coolant flows into the interior of the block from different directions. Also described is a method of cooling a device such as a processor of a mobile computer used in a vehicle by placing the heat sink or more than one of the heat sinks adjacent to the device to be cooled, preferably with a region in which the venturi narrowing of the coolant channels is provided close to the hottest part of the device to be cooled.
