Abstract: A voltage level translator provides an output signal having an external voltage in response to an input signal having an internal voltage. The voltage level translator includes first and second input signal transistors, first and second output signal transistors, and includes a signal stabilization circuit and/or an enable circuit. A ready-signal generation circuit provides a ready signal indicating that a voltage supply is at an operating voltage. The ready-signal generation circuit can include unbalanced transistors.

Abstract: An electronic device, such as a microprocessor, with a timing circuit. The timing circuit contains a phase locked loop that, during a first interval, checks whether a control signal in the phase locked loop is between a maximum allowed value and a minimum allowed value. When the control signal in the phase locked loop is above a maximum allowed value or below a minimum allowed value, the control circuit disables the phase locked loop for a second interval. When the control signal in the phase locked loop is below a maximum allowed value and above a minimum allowed value, the timing circuit indicates that the output of the phase locked loop is stable.

Abstract: A system for verifying the identification of a device. A codec is configured to measure at least one electrical characteristic of a device connected to a jack and to identify the device based on the measured electrical characteristic. An updateable database is populated with the electrical characteristic of at least one device whose electrical characteristic was measured by the codec but not correctly identified by the codec and a software routine is responsive to the measured electrical characteristic and configured to adjust the codec's identification of the device based on the electrical characteristic stored in the database to correctly identify the device.

Abstract: A system and method for determining the true electrical characteristics of a device. A codec is configured to measure at least one electrical characteristic of a device connected to a jack and to identify the device based on the measured electrical characteristics. An updateable database is populated with application circuit information and a software routine is responsive to the measured electrical characteristic and configured to adjust the electrical characteristics measured by the codec based on the application circuit information in the database.

Abstract: An identification system and method for recognizing a device as one of a plurality of different types of devices connected to at least one terminal of an information handling system includes supplying a test signal to a device in a test mode; measuring an electrical characteristic of the device in response to the test signal being applied to the device in the test mode; and matching a representation of the electrical characteristic of the device with representations of the electrical characteristics of the plurality of devices for recognizing the device connected to the terminal as one of the plurality of different devices.

Abstract: An apparatus for guiding the resection of the head of a humerus is provided. The apparatus includes a base, a cut block, and a stylus. The guide is used in connection with a reamer or other tool that is inserted into the intramedullary mayal of the humerus with the shank of the reamer extending superiorally above the head of the humerus to establish the axis of the humerus. The base is in rotatable connection with the reamer. The cut block is removably attached to the guide and has a component for receiving a saw blade. The stylus attaches to the cut block, preferably by engaging the component for receiving the saw blade, and extends around the articular margin of the humeral head to aid in setting height and version.

Abstract: A series of humeral stems, each stem including an axial bore and longitudinal slots along the distal end to allow for distal compression. The compression force necessary to compress the distal diameter of each stem varies by stem diameter. Thus, as the stem diameter increases through the series, the compression force decreases. The axial bore and longitudinal slots together form a series of stem segments that assume the shape of the medullary canal, reducing the force exerted upon the canal by the humeral stem.

Abstract: A suspension limiter for limiting travel of a read/write transducer gimbal in a disc drive is disclosed that positively engages or interlocks with a feature of the load beam supporting the gimbal, or vice versa, to preclude disengagement of the limiter during an abnormal external shock event. One embodiment has a hook on the load beam that fits within a hole gimbal to interlock the two together. Another embodiment has a hook on the gimbal that fits within a hole in the load beam during a shock event. Another embodiment has tabs on the gimbal that hook over a notch in side fingers extending from the end of the load beam on either side of the gimbal. Another embodiment has a hooked tab on the load beam that extends through an aperture in the gimbal to interlock the gimbal and load beam together during a shock load event. Each of the embodiments prevents catastrophic plastic deformation of the gimbal during such events.
