| 20100197082 | Implantable Microelectronic Device and Method of Manufacture - An implantable hermetically sealed microelectronic device and method of manufacture are disclosed. The microelectronic device of the present invention is hermetically encased in a insulator, such as alumina formed by ion bean assisted deposition (“IBAD”), with a stack of biocompatible conductive layers extending from a contact pad on the device to an aperture in the hermetic layer. In a preferred embodiment, one or more patterned titanium layers are formed over the device contact pad, and one or more platinum layers are formed over the titanium layers, such that the top surface of the upper platinum layer defines an external, biocompatible electrical contact for the device. Preferably, the bottom conductive layer is larger than the contact pad on the device, and a layer in the stack defines a shoulder. | 08-05-2010 |

| 20110002270 | BASE STATION AND METHOD FOR REDUCING ASYNCHRONOUS INTERFERENCE IN A MULTI-TIER OFDMA OVERLAY NETWORK - Embodiments of a base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network are generally described herein. In some embodiments, a lower-tier base station is configured to adjust OFDMA frame boundaries to cause frames communicated by a higher-tier to arrive within a cyclic prefix at the lower-tier base station. The lower-tier base station may also be configured to adjust OFDMA frame boundaries to cause frames communicated by a lower-tier of the network to arrive within a cyclic prefix at a higher-tier mobile station. Accordingly, frames from one tier may arrive within the cyclic prefix of another thereby reducing asynchronous interference. | 01-06-2011 |

| 20090171514 | METHOD FOR IMPROVING THE PRECISION AND RELIABILITY OF CIRCUIT HEATING CONTROL THROUGH A 1 - WIRE SENSOR - A method for improving the precision and reliability of the heating control for an anesthetic machine circuit, comprises: a 1-wire temperature sensor is positioned in the anesthetic machine circuit and electrically connected to a control unit. The control unit reads the ID and verification code of the temperature sensor according to 1-wire protocol and determines the validity of the temperature sensor. The control unit reads the temperature value of the temperature sensor and compares it with the target control temperature. The control unit then turns on the control switch when requiring heating such that power supply powers the heater and the circuit temperature rises, or on the contrary turns off the control switch and the circuit temperature drops according to a control algorithm. The average power of the heater is controlled by PWM method such that the circuit is operated at a predetermined control temperature. With the usage of the 1-wire temperature sensor, the problem of analog signal transmission error is solved, the use of the sensor is facilitated, a long-distance temperature detection and control is obtained. At the same time the digital signal form and interface protocol of the sensor have relative higher anti-disturbance performance and failure recognition function. Accordingly, the requirement on the interface connection quality is reduced, and the reliability is improved. | 07-02-2009 |
