Abstract: An electronic device with a microphone, a speaker, a processor, and a power tool battery pack connectable to and powering the speaker and the processor. The electronic device has software that can cause the processor to perform operations which can cause the electronic device to operate in first and second modes. While the electronic device is operating in the first mode, the device can generate first audio data representing user speech captured by the microphone which can be analyzed by the electronic device or a remote server. The electronic device can switch from operating in the first mode to operating in a second mode, where the electronic device can receive, second audio data from another electronic device. The electronic device can then output, using the speaker, audible content represented by the second audio data.

Abstract: Methods, systems, and devices are provided for tire pressure detectors that may operate according to one of two or more selectable frequencies. Tire pressure detectors may include an RF section to modulate pressure information from a pressure sensor onto an output signal. The frequency of the output signal may be selectable from two or more frequencies based on a frequency required by a vehicle that the tire pressure detector is to be used with. An RF matching circuit may be coupled between the RF section and an antenna, with an impedance of the RF matching circuit selected based of the frequency of the output signal. Such impedance matching may provide a constant power level output from the tire pressure detector independent of the frequency of the tire pressure detector transmissions.

Abstract: A data detection system includes, in part, a CID detector, a DC balance monitor and a transition density detector. The CID detector is configured to detect whether the received data stream includes a CID exceeding a predetermined threshold count. The DC balance monitor is configured to detect DC imbalances in the incoming data and that may be indicative of errors in the data. The transition density detector is configured to detect whether a minimum transition density exists during a given time period. If a violation is detected by any one of these three detectors, an out-of-frame signal is asserted. The incoming data stream may be a scrambled SONET or SDH data stream.

Abstract: A breathing apparatus comprises at least one spherical container (15) for breathable gas attached to a harness (1,9,20,21) (5) (109) for securing the same to a user. Each container may be located within a protective casing (14,14′) and is preferably formed of composite material.

Abstract: A harness to enable the wearer to carry an article such as breathing apparatus comprises a waist belt (9) carrying a waist plate (1) to which a back plate (21) is secured. The harness includes shoulder straps (20) and a coupling (41,50) for securing the article to it. The back plate (21) is moveable with respect to the waist plate (1) to facilitate movement of the wearer's body.

Abstract: Apparatus for producing a light mask for balancing light across a display area of a vehicle instrument cluster comprises a camera, a digitiser and a computer. An image of the display area is obtained and digitized to produce data relating to the illumination levels of the image at a plurality of pixels. The illumination levels are used to calculate an appropriate light mask for the display area on the basis of the transmissive density of the masking ink used and or a reference illumination value relating to the least lit part of the display area which it is desired to illuminate. The light mask comprises an array of dots having a diameter related to the amount of attenuation required in the area in which the dot is located. Up to three masking layers may be provided if a single layer is insufficient to produce the required attenuation with the chosen masking ink. Balanced coverlays can readily be produced, and the number of masking layers required can also be reduced.
