A method of regulating voltage includes closing first and second switching devices during first and second periods in response to first and second signals, respectively. The first and second switching devices open and close to connect and disconnect first ends of first and second inductors of first and second phases of a voltage regulator to and from an input voltage, respectively. The method includes selectively generating one of the first and second signals when a third signal is in a first state; selectively setting the third signal to the first state based on a ramp voltage; resetting the ramp voltage to a predetermined reset voltage when the third signal transitions from a second state to the first state; maintaining the ramp voltage at the predetermined reset voltage for a predetermined ramp reset period after the resetting; and increasing the ramp voltage after the predetermined ramp reset period.

A mobile device with orientation aware audio mapping capability is disclosed. The mobile device has an aux speaker, a loud speaker, a sensor for device orientation detection, and a processor (or processors) coupled to the sensor and the speakers. Depending on the device orientation, the processor sends a mapped audio output to the speakers. The mapped audio output may be a mono audio signal or a stereo audio signal. The stereo audio output signal may be a stereo audio output signal with a balanced or biased audio power distribution between the aux speaker and the loud speaker.

A temperature measurement footprint device, a mobile temperature measurement device, and a method for determining a temperature measurement footprint are described. In an implementation, a temperature measurement footprint device includes a thermopile configured to measure a temperature of an object; a camera configured to capture an image of the object, the camera disposed proximate to and in communication with the thermopile; and a light source configured to illuminate the object, the light source disposed proximate to and in communication with the thermopile and the camera.


A system includes a clock interconnect network having an input node and a plurality of output nodes. The clock interconnect network receives a clock input at the input node and distributes, based on the clock input, a plurality of clock signals via respective ones of the plurality of output nodes. A propagation delay of each of the plurality of clock signals distributed by the clock interconnect network is approximately equal to respective propagation delays of others of the plurality of clock signals distributed by the clock interconnect network. A digital-to-analog converter includes a plurality of segments, each outputting a respective output, and a plurality of drivers. Each of the plurality of drivers receives a respective one of the plurality of clock signals and provides a driver signal to a respective one of the plurality of segments based on the respective one of the plurality of clock signals.

A customer mobile personal point-of-sale terminal (CMPPT) includes a Point-Of-Sale (POS) sleeve portion that slidingly engages, and couples to, a cellular telephone. The cellular telephone is used to communicate encrypted information between a financial transaction verification entity (FTVE) and the POS sleeve portion. The sleeve portion includes a mechanism for reading in a merchant account number at the point-of-sale, and for communicating in a secure encrypted fashion with the FTVE via the cellular telephone portion. Rather than a customer entering sensitive financial information into a merchants POS terminal (MPT) and trusting the merchant with such information, merchant information is entered into the CMPPT. The CMPPT initiates a transaction by sending the customers account information and the merchant information to the FTVE. The FTVE receives information about the transaction directly from the MPT. The FTVE verifies the transaction, and after authorization, the FTVE forwards approval codes to the CMPPT and MPT.

A micromechanical Coriolis rate of rotation sensor for detecting a rate of rotation, comprising a substrate, a measurement axis, a detection axis, and a drive axis, each disposed orthogonally to each other and a first and a second driving mass disposed in a plane parallel to the substrate. Each driving mass being rotatably connected to the substrate by means of a central suspension. The two central suspensions being disposed along the detection axis. Drive electrodes generate rotary motions of the driving masses about the drive axis at each central suspension. Elastic connecting elements are disposed on each of the driving masses on both sides of the detection axis to connect and oscillate the two driving masses to synchronize their rotary motions.
