Abstract:
Analog-valued floating-gate transistors are used as trimmable circuit components for modifying and/or controlling the gain, phase, offset, frequency response, current consumption, and/or transfer function of signal pathways in parallel and/or serial processing circuits in radio frequency, analog, or mixed-signal integrated circuits.

Abstract:
Methods of and apparatuses for optimizing quantization noise cancellation in multi-phase sampled MASH ADCs are disclosed. A test signal is combined with quantization noise produced by a delta-sigma modulator. Two parallel adaptive filters (i.e. even and odd filters) are configured to receive respective even and odd samples of a digital output signal of a MASH ADC analog modulator. Adaptive coefficients for the even adaptive filter are derived from correlation results between the even samples of the test signal and associated even samples of the final digital output signal. Similarly, adaptive coefficients for the odd adaptive filter are derived from correlation results between the odd samples of the test signal and associated odd samples of the final digital output signal. Using the adaptive coefficients, the even and odd adaptive filters are able to independently compensate for analog variations in the two paths. Fixed, slowly varying, and clock rate variations may all be tracked out using the methods and apparatus of the present invention.
Abstract:
An apparatus (21) and method for rapid transport of elastic bands (34) from a band loading station (22) to a band unloading station (23). The apparatus (21) includes a movable arm assembly (24) having a finger (26) thereon dimensioned to loosely receive an elastic band (34) therearound. A drive assembly (36) is coupled to move the arm assembly (24) from the loading (22) to the unloading station (23). The arm assembly (24) is further movable by the drive assembly (36) from a first orientation of the finger (26) to a second orientation of the finger (26) to enable gravity assisted mounting of the band (34) on the finger (26) at the loading station (22) and gravity assisted demounting of the band (34) at the unloading station (23). During the transport of the band (34) between the loading (22) and unloading stations (23), the finger (26) is reoriented along a path maintaining the band (34) on the finger (26) against dynamic forces acting on the band (34) during transport of the arm assembly (24). The apparatus (21) includes a gear train (43, 44, 53, 62) which simultaneously pivots the arm assembly (24) between the loading (22) and unloading station (23) while it rotates the arm (24) in a direction opposed to the pivoting to maintain the band (34) on the finger (26) during pivoting of the arm (24).
Abstract:
Methods and apparatus to identify users of handheld computing devices are disclosed. An example method includes generating, via a logic circuit, a first handling pattern indicative of a manner in which a handheld computing device is moved while the handheld computing device is presenting media; and storing the first handling pattern and corresponding user identification information in a database, handling patterns stored in the database to identify users of the handheld computing device.
Abstract:
Methods, apparatus, systems and articles of manufacture to monitor media presentations are disclosed. An example method includes collecting demographic information from a user. The demographic information is transmitted to a central facility. A panelist identifier identifying the user is generated. The panelist identifier is stored in a shared memory of the media device, the panelist identifier to be retrieved by a monitoring enabled application, the monitoring enabled application to collect monitoring information if the panelist identifier is in the shared memory and to disable collection of the media monitoring information if the panelist identifier is not in the shared memory.
Abstract:

Abstract:
A method for making a polystyrene ionomer comprises: preparing a metallic comonomer within styrene monomer to form a reaction mixture; and placing the reaction mixture under conditions suitable for the formation of a polymer composition. The metallic comonomer can be a metal acrylate, formed by contacting a metal complex and an acrylate precursor.

Abstract:
The invention comprises a golf ball. The golf ball is formed with a core, at least one intermediate layer, and a cover. The intermediate layer has a non-planar parting line. The molds used to form the intermediate layer have non-planar mating surfaces. The non-planar mating surfaces of the molds mesh, and when the intermediate layer is formed therein, the intermediate layer has a non-planar parting line thereon. If compression molding is used, hemispherical layer blanks may be pre-formed in the shape of the mold halves. To form the intermediate layer, the two blanks are compression molded together. If injection molding is used, a core is placed inside a mold chamber and layer material is injected into the mold chamber to form the intermediate layer about the core. If reaction injection molding is used, two or more reactive precursors are mixed and injected into the mold cavity, and they react to form the intermediate layer. Optional outer layers and a cover are molded on the intermediate layer to form a finished ball.
