A method and apparatus for monitoring and controlling reactive sputter deposition, particularly useful for depositing insulating compounds (e.g., metal-oxides, metal-nitrides, etc.). For a given nominal cathode power level, target material, and source gases, the power supplied to the cathode (target) is controlled to stabilize the cathode (target) voltage at a specified value or within a specified range corresponding to a partial pressure or relative flow rate value or range of the reactive gas. Such an operating point or range, characterized by a specified voltage value or range and corresponding reactive gas relative-flow / partial-pressure value or range, may be determined empirically based on measuring the cathode voltage as a function of reactive gas relative-flow / partial-pressure for the given nominal power. This relationship is typically a hysteresis curve, and preferably the operation point is selected at or near the hysteresis transition edge to provide high rate deposition of high quality films, including insulating or dielectric films using a metallic target.

The absorbent article exhibits a cuff height ratio, defined as a cuff height as measured at the crotch point divided by a minimum cuff height as measured in the end region, of greater than 1.

A demodulation circuit for an Amplitude Shift Keyed (ASK) modulated signal includes an envelope detector, an alternating voltage amplifier, a differentiator circuit, and a comparator having a hysteresis connected in series. The envelope detector produces an envelope signal from the received ASK signal. The amplifier blocks the DC component of the envelope signal and amplifies AC components of the envelope signal to obtain a steeper slope of the rising and falling edges. The differentiator circuit then processes the transition edges to provide a differentiated signal having positive and negative electrical pulses. The comparator converts the pulses into a binary data stream which corresponds to the transmitted data stream. The combination of the differentiated signal and comparator having a hysteresis enables better stability and sensitivity of the ASK demodulation circuit.

Clock signals are supplied, with a phase shift of 1 / n cycles between adjacent clock signals. A data acquisition unit acquires serial data at a timing of each of the clock signals. A phase detection unit detects the phase of the transition edge of the serial data using n bits of data. An effective bit number determination unit determines the effective bit number, which is the number of bits to be acquired, based upon the phase of the transition edge of the serial data in the current data-bit acquisition step and the phase of the transition edge of the serial data in the previous data-bit acquisition step. A data-bit output unit outputs the effective bit number of the bits of data acquired at a timing of each clock signal having a predetermined phase relation with the transition edge of the serial data.

A prosthetic patellar component includes a base and a bearing element that includes first and second femoral engaging surfaces disposed between first and second (superior / inferior) edge surfaces. The edge surfaces are curved to provide a gradual transition from a posterior facing portion to a nearly vertical superior or inferior facing portion. Moreover, the inferior-superior dimension of the component is at least approximately 90% of the medial-lateral dimension. The relative height and gradually transitioning edges significantly reduce the likelihood of sudden posterior rotation during deep flexion movement. The edge surfaces extend from a substantially posterior facing portion proximate to the first and second femoral engaging surfaces and a substantially vertical facing portion proximate the base. The curved edge surfaces can include a plurality of adjacent medial-laterally extending surface portions having angular displacement relative to an adjacent surface portion of less than 30 degrees in the anterior-posterior direction.

A stream of data may flow over a fiber or other medium without any accompanying clock signal. The receiving device may then be required to process this data synchronously. Embodiments describe clock and data recovery (CDR) circuits which may sample a data signal at a plurality of sampling points to partition a clock cycle into four phase regions P1, P2, P3, and P4 which may be represented on a phase plane being divided into four quadrants. A relative phase between a data signal transition edge and a clock phase may be represented by a phasor on the phase plane. The clock phase and frequency may be adjusted by determining the instantaneous location of the phasor and the direction of phasor rotation in the phase plane.

An optical disc is provided with an associated optical shutter. In a first state, the optical media interferes with the ability of an interrogating laser beam to read data from the optical media, and in a second state, the optical media is substantially transparent, enabling the laser beam to read the disc. A powering circuit is used to cause the optical shutter to transition from a first state to the second state. In one example, an integrated circuit acts as the powering circuit, as well as providing logic and processing functions. The integrated circuit also couples to an RF antenna, enabling the integrated circuit to communicate with an associated RF scanning device. The optical shutter may take various geometric shapes, and typically has an electrochromic material for facilitating state change. The electrochromic material may fill the shutter, or the material may form a pattern. The shutter may be positioned on the disk so that transition edge-effects are reduced, allowing for reduced interference with the laser beam when the optical shutter is in its clear state. The optical shutter does not cover the entire data area of the disc, and in one example, the optical shutter is quite small, allowing for lower cost production, as well as reducing power requirements to transition the electrochromic material. Power requirements may be further reduced by forming the electrochromic in a pattern. A small optical shutter may disable reading of disc, for example, by placing the small shutter over an important section of the disc, such as the lead-in area.

A test method is for determining RF path loss between an RF source and an RF receiver. The RF source may transmit RF power values at a relatively fine granularity, and the RF receiver may generate RSSI values at a relatively coarse granularity and have an unknown hysteresis about each transition between adjacent RSSI values. Hysteresis edges may be determined about a given RSSI value transition at the RF receiver by sweeping RF power values transmitted from the RF source in increasing and decreasing directions. A relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values may be determined using the hysteresis transition edges. The RF path loss for a given channel may be determined based upon a given RSSI at a given RF power value and the relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values.
