Abstract: Fair usage of working channels in a wireless network is disclosed. A base station associated with a cell within a wireless community monitors the congestion of the working channel of neighboring communities. Upon determining that the congestion of the working channel of a neighboring community is less than that of its existing working channel, the base station initiates a switch to the neighboring community's working channel. Upon joining the new community, the frame structure and other networking parameters and attributes are adjusted.

Abstract: A semiconductor device includes a semiconductor material substrate, an opto-electric component formed on the substrate, and a first transparent layer formed on an upper surface of the substrate over the component, the layer having a planar upper surface with a cavity formed therein. The first transparent layer has a selected thickness and a first index of refraction. The semiconductor device further includes a lens having a second index of refraction, the lens being formed in the cavity by flowing a flowable dielectric over the substrate. An upper surface of the lens and the upper surface of the transparent layer may be coplanar, or alternatively, they may lie in separate planes. The semiconductor device may also include a second transparent layer formed over the first layer and lens, as a passivation layer.

Abstract: A digital-to-analog converter, in response to a digital signal, selectively taps a resistor string to generate an analog output and selectively shunts around resistors in the string to voltage shift the analog output. If two supply voltage sets are present, two strings are provided. A mutually exclusively selection of outputs is made to select a source of the analog output. An integrated circuit temperature sensor uses the converter and includes a sensing circuit that determines exposure to one of a relatively low or high temperature. A measured voltage across the base-emitter of a bipolar transistor is selected in low temperature exposure and compared against a first reference for a too cold temperature condition. Alternatively, a measured delta voltage across the base-emitter is selected in high temperature exposure and compared against a second reference voltage for a too hot temperature condition. Through the comparisons, a temperature exposure detection is made.

Abstract: A protective barrier layer, formed of a material such as titanium or titanium nitride for which removal by chemical mechanical polishing (CMP) is primarily mechanical rather than primarily chemical, formed on a conformal tungsten layer. During subsequent CMP to pattern the tungsten layer, upper topological regions of the protective barrier layer (such as those overlying interlevel dielectric regions) are removed first, exposing the tungsten under those regions to removal, while protective barrier layer regions over lower topological regions (such as openings within the interlevel dielectric) remain to prevent chemical attack of underlying tungsten. CMP patterned tungsten is thus substantially planar with the interlevel dielectric without dishing, even in large area tungsten structures such as MOS capacitor structures.

Abstract: Disk drive spindle jitter is comprised of electrical noise, error due to pair pole asymmetry, and random disk speed variances. Error caused by pair pole asymmetry can be identified and compensated for by detecting over a single rotation of a rotor a plurality of zero cross signals. These signals can be statistically analyzed over a period of a plurality of revolutions of the rotor so as to identify the systematic error caused by pair poles. Once identified, this pair pole error can be used to modify zero cross signals and/or modify commutation signal driving the disk so as to arrive at a more accurate determination of disk speed and to precisely control the speed of the disk.

Abstract: Connection between optical fibers and optical components within a semiconductor substrate. A lens is created at the front of a semiconductor substrate. A tapered hole is created in the back of the substrate exposing part or all of the surface of the lens. An optical component is formed or affixed at the front surface of the substrate. A volume of transparent adhesive is placed in the hole, followed by an optical fiber, which is thus coupled to the surface of the lens. A light guide is created on the front of the substrate overlying the lens to direct optical signals between the optical fiber inserted in the tapered hole and the optical component on the surface of the substrate.

Abstract: A write driver for driving a write current through a write head connected to the write head by an interconnect or flexible transmission line. The write driver includes a circuit matching an output impedance of the write driver to the odd characteristic impedance of the interconnect and includes a current source generating a current output to the write head. The write driver provides a current amplification effect as the output current is half the write current driven through the write coil. The impedance matching circuit includes an output resistor with a resistance equal to the odd characteristic impedance of the interconnect. The write driver includes a voltage source that operates to maintain a voltage drop of zero on the output resistor during the initial period of twice the transmission delay of the interconnect.

Abstract: A key switch matrix circuit includes key switches arranged in rows and columns, each row having a scan line, each column having a sense line. Each key switch is operable to couple a scan line to a sense line. A scan signal delivery circuit supplies scan signals to the scan lines, the scan signals delivering a scan pulse to each row of the key switch matrix circuit in turn. A key switch detection circuit outputs a first signal if a key switch is operated and a scan pulse detection circuit outputs a second signal if a scan pulse is coupled to a sense line. The scan signal delivery circuit begins supplying scan signals in response to the first signal and stops supplying scan signals in response to the second signal. In one embodiment, a processor reads the sense lines in response to the second signal.

Abstract: An integrated circuit (IC) may include at least one smart card memory for storing a set of default requests and at least one alternate request for each default request. The IC may further include a microprocessor connected to the at least one smart card memory for communicating with a host device using the default requests and alternate requests. The microprocessor may selectively switch between using the default requests and the alternate requests when communicating with the host device. As such, this provides a “moving target” which makes it difficult for would-be hackers to determine which requests are used for which smart card operations and, thus, to decipher and interfere with data communications.
