IPC: A61B17/32
Filed: 2005-10-19
Abstract: [00128] A surgical knife safety device (10 or 100) having a handle (20 or 120), a blade (40 or 140) connected to the handle, and a guard (30 or 130) carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard (30 or 130) radius is provided at the distal end of the handle (20 or 120) to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder (26 or 126), preventing unwanted blade or handle movement due to guard mechanism tolerances. A spring, such as leaf spring or a cantilever beam (52 or 152), and a pair of detents (54, 56) or slots (154, 156) are provided to fix the guard (30 or 130) in the extended or retracted position and to provide resistance during movement between the two positions. Additionally, a pushback prevention mechanism, a user operable lock and a drop-force operable lock are provided to prevent accidental retraction of the guard from the fully extended and guarded position.

Inventor: LARSSON PETER
IPC: H04L27/26
Filed: 2004-12-21
Abstract: In a communication system, when packet data units (PDUs) to be transmitted from a transmitter apparatus are modulated according to Orthogonal Frequency Division Multiplexing (OFDM), the waveforms representing the modulated PDUs will experience different peak to average ratio values (PAR) making the PDUs differently sensitive to non-ideal transmitter characteristics. To minimize errors in the transmitted PDUs, at least two PDUs (304, 305, 306) are scrambled and modulated in parallel and substantially simultaneously in the transmitter (100), and the PAR values of the at least two PDUs (304, 305, 306) are determined at each transmit instance. The measured PAR values of the at least two PDUs are compared in a scheduler (310), and the scheduler selects for transmission the PDU with the lowest PAR value. The scheduler (310) then instructs the transmitter (100) to transmit the selected PDU. If the PDUs that were not selected for transmission are re-scrambled and re-modulated before they are transmitted, the average PAR value for a transmitted PDU can be lowered by 2-3 dB with the invention if 8 PDUs are compared at each transmit instance.

Abstract: An improved tool assembly for enhancing the surface of a heat transfer tube is provided. The tool assembly includes rods having cutting tips and positioned in rod guides which are slidably positioned in shafts provided in a tool holder. In an equilibrium state, the cutting tips do not extend from the tool holder. When a force is applied to the rod guides, the rod guides move in a first direction along the shafts in the tool holder, resulting in exposure of the cutting tips which enhance the tube surface. When the force is removed from the rod guides, the rod guides move along the shafts in a direction opposite the first direction to retract the cutting tips within the tool holder. In this way, the cutting tips are protected when not in use.

Title: Device and method for the demodulation of modulated electromagnetic wave fields
Inventor: BUTTGEN BERNHARD
IPC: H01L27/146
Filed: 2006-10-06
Abstract: A new pixel in semiconductor technology comprises a photo-sensitive detection region (1) for converting an electromagnetic wave field into an electric signal of flowing charges, a separated demodulation region (2) with at least two output nodes (D10, D20) and means (IG10, DG10, IG20, DG20) for sampling the charge-current signal at at least two different time intervals within a modulation period. A contact node (K2) links the detection region (1) to the demodulation region (2). A drift field accomplishes the transfer of the electric signal of flowing charges from the detection region to the contact node. The electric signal of flowing charges is then transferred from the contact node (K2) during each of the two time intervals to the two output nodes allocated to the respective time interval. The separation of the demodulation and the detection regions provides a pixel capable of demodulating electromagnetic wave field at high speed and with high sensitivity.

Filed: 2007-06-01
Abstract: Electrically powered electromagnetic field source beacons installed in a reference well in combination with a down-hole measurement while drilling (MWD) electronic survey instrument near the drill bit in the borehole being drilled permit distance and direction measurements for drilling guidance. Ea ch magnetic field source beacon consists of a coil of wire wound on a steel coupling between two lengths of steel tubing in the reference well, and powered by an electronic package. Control circuitry in the electronic packag e continuously "listens" for, and recognizes, a "start" signal that is initiat ed by the driller. After a "start" signal has been received, the beacon is energized for a short time interval during which an electromagnetic field is generated, which is measured by the MWD apparatus. The generated magnetic field may be an AC field, or switching circuitry can periodically reverse th e direction of a generated DC electromagnetic field, and the measured vector components of the electromagnetic field are used to determine the relative location coordinates of the drilling bit and the beacon using well-known mathematical methods. The magnetic field source and powering electronic packages may be integral parts of the reference well casing or may be part o f a temporary work string installed therein. Generally, numerous beacons will be installed along the length of the reference well, particularly in the important oil field application of drilling steam assisted gravity drainage (SAGD) well pairs.
