摘要： Systems and methods for accurate temperature modification of a patient, or selected regions thereof, including inducing hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. A temperature measurement scheme for obtaining body core temperature is provided, including methods of obtaining and analyzing temperature data to provide feedback to the control unit for use in controlling the heating and cooling of the heat exchange medium so as to heat or cool a patient to a desired target temperature.

摘要： A method and system are provided for creating and utilizing subscriber specific memory locations or storage folders for storing incoming voicemail messages in a telecommunications system voicemail system. A subscriber to voicemail services creates subscriber or user-specific memory locations or storage folders to which callers may direct a voice message. When a caller calls the subscriber's directory number and is forwarded to the subscriber's voicemail service, the caller is given the option to save the message in one of a number of previous created voice message folders. For example, the caller may receive a prompt like “Press I to leave a message for Jane.” If messages are inadvertently left in the wrong voice message folder, the user having authorized access to that folder may move the message to the appropriate folder. If desired, personal identification numbers (PIN) may be assigned to each voice message folder to control access to messages saved therein.

摘要： System and method for providing power with a large on-current and small off-current to circuitry in an integrated circuit. A preferred embodiment comprises a switch for providing power to circuits in an integrated circuit made from a PMOS transistor and an NMOS transistor coupled in parallel. Each transistor's gate terminal is coupled to a separate control signal line. The PMOS transistor provides current to the circuits at high voltage supply levels while the NMOS transistor provides current to the circuits at low voltage supply levels, wherein the size of the PMOS and NMOS transistor can be changed during design to meet power requirements. Depending upon power requirements, multiple PMOS and NMOS transistors may be used. The combination of PMOS and NMOS transistors permit the use of limited fabrication processes wherein transistor widths can be limited.

摘要： A digital dual-band detector functions as an imaging platform capable of extracting hard and soft tissue images, for example. The detector has a first detector system comprising a first scintillator for converting x-rays from a sample to an first optical signal, and a first detector for detecting the first optical signal in combination with a second detector system comprising a second scintillator for converting x-rays from the sample and passing through the first scintillator to a second optical signal, and a second detector for detecting the second optical signal. The detector can facilitate the implementation and deployment of recent developments and can permit low cost practical deployment in clinical applications as well as biomedical research applications where significant improvement in spatial resolution and image contrast is required. These improvements include an increase of feature detection sensitivity by more than an order of magnitude, simultaneous imaging of soft and hard (or mineralized) tissue at extremely high time resolution that is not limited by detector readout speed, and an increase in the signal to noise ratio of images by reducing the substantial background resulting from Compton scattering.

摘要： A Mach-Zehnder modulator that employs quantum dots to provide a push-pull drive operation. The Mach-Zehnder modulator includes a first arm having a first PIN semiconductor device and a second arm having a second PIN semiconductor device, where the intrinsic layers of the PIN devices include a quantum dot structure. A first DC bias signal is applied to one of the PIN devices, and a second DC bias signal is applied to the other PIN device. The first DC bias signal biases the intrinsic layer at an operating voltage where the index of refraction of the intrinsic layer is at a positive portion of an electro-refraction transfer function, and the second DC bias potential biases the intrinsic layer at an operating voltage where the index of refraction of the intrinsic layer is at a negative portion of the transfer function.

摘要： The present invention provides a method (100) of designing a circuit. The method comprises specifying (105) a design parameter for memory transistors and logic transistors and selecting (110) a test retention-mode bias voltage for the memory transistors. The method further comprises determining (115) a first relationship of a retention-mode leakage current and the design parameter at the test retention-mode bias voltage and obtaining (120) a second relationship of an active-mode drive current and the design parameter. The first and second relationships are used (125) to assess whether there is a range of values of the design parameter where the retention-mode leakage current and the active-mode drive current are within a predefined circuit specification. The method also includes adjusting (130) the test retention-mode bias voltage and repeating the determining and the using if the retention-mode total leakage current or the active-mode drive current is outside of the predefined circuit specification.

摘要： System and method for reducing voltage fluctuations in an integrated circuit with multiple power domains and sub-domains. A preferred embodiment comprises a plurality of voltage sources and a switching network (such as switching network 320) wherein outputs from the plurality of voltage sources are inputs. The switching network can couple the outputs of voltage sources (based on a mapping) with the same output voltage levels to reduce voltage fluctuation amongst power domains coupled to the coupled outputs. The coupling may be performed by a switching structure (such as the switching structure 215) that can controllably electrically couple two outputs.

摘要： A PIN electro-optical traveling wave modulator (10) including diffraction gratings (34, 36) positioned at opposing sides of an optical waveguide (20) that act to change the propagation pattern of the waveguide (20). The modulator (10) includes an N-type layer (14), a P-type layer (18) and an intrinsic layer (16) acting as the waveguide (20). A metal electrode (26) is in electrical contact with the N-type layer (14), and a metal electrode (30) is in electrical contact with the P-type layer (18). The electrodes (26, 30) define an RF transmission line. An optical wave (22) propagates along the waveguide (20) and interacts with the gratings (34, 36) which slow the optical wave (22) to match its speed to the speed of the RF wave in the transmission line. In one embodiment, the gratings (34, 36) are 2-D gratings formed by vertical holes (38) in the waveguide (20).
