IPC: H03F3/217
Filed: 1992-09-18
Abstract: An amplitude regulation circuit (REG) is presented which regulates towards a reference amplitude (VR) an amplitude of a pulse waveform which is generated across a load impedance (L) by a so-called H-bridge, at least one of whose switches has a variable impedance. The amplitude regulation circuit (REG) includes a measuring means (C1) measuring said amplitude during first parts of said pulse waveform and a regulating means (OA, C2, CS1, S2, S3, Q5, CS2, S4, S5, Q6) which is controlled by said measuring means (C1) during second parts of said pulse waveform and which regulates said variable impedance, thereby regulating said pulse waveform amplitude.

Abstract: An ophthalmological laser surgery system having a laser, associated elements for delivering an optical beam from the laser to a patient eye location, a control unit for controlling the operation of the system and a system input/output device, is enabled by a patient data card. The data card originally contains both patient background and system control information, which is transferred to the control unit via the input/output device. During system operation, newly generated information, such as laser beam power, is stored in the data card to provide an independent record of the surgical procedure actually performed. After one use, the data card is invalidated to prevent further use.

Title: Uphole hammer
Inventor: REAR IAN GRAEME
IPC: E21B4/14
Filed: 1992-04-03
Abstract: An uphole hammer comprising a substantially tubular housing (11) which is closed at one end and supports a substantially centrally located fluid supply tube (13) at said one end, wherein said fluid supply tube extends axially through the housing and is adapted to be counted at its other end to a drill string, said fluid supply tube being adapted to receive fluid being directed to the hammer by the drill string, said housing further supporting a drill bit (18) at or towards its other end which is slidably received about the fluid supply tube, a piston (27) also being slidably supported about the fluid supply tube in the housing for reciprocation between the drill bit and said one end of the housing, and fluid porting means (33,34) being provided to alternately admit fluid to the spaces defined between each end of the piston and the respective ends of the housing to effect reciprocation of the piston between a first position at which it impacts on the drill bit and a second position at which it lies in the vicinity of said one end of the housing.

Abstract: An orthosis (10) for stretching tissue that limits compressive forces on the soil tissue around a joint during movement of the joint. The orthosis includes two relatively pivotable cuff arms (22,40) with a cuff (12,16) on each arm. The cuffs clamp onto the body portions on either side of the joint. The pivot axis (D) of the cuff arms is spaced from the pivot axis (A) of the joint, so that movement of the cuff arms to extend the joint results in distractive forces being applied to the joint. The cuffs are selectively moved on the cuff arms, during extension and flexion, to provide the proper amount of distractive forces to the joint and to limit compressive forces on the joint. A mechanical advantage is gained through the use of a gear drive mechanism for transmitting to the joint the force applied by the patient. This allows the orthosis to be relatively small and lightweight. The orthosis also provides a portable system for continuous passive motion therapy for a joint. The orthosis may be operated by a manual plus electric drive cycling it between extremes of motion. Provision is made for monitoring the range of motion or the force applied.

Abstract: A dither signal (18) is applied to a sigma-delta modulator (9) to remove low level tones and periodic noise in the desired passband of the modulator when no, or a very low, signal is present (idle). The dither signal is a high-level signal added to the input of a quantizer (16) in the modulator, the normalized in the AC component thereof being at least about               2       -2(N-1)           12               of the square of the quantizer step, where N is the order of the modulator. No significant reduction in the dynamic range of the modulator results. The technique may also be applied to multiple order sigma-delta modulators as well as to multiple stage sigma-delta modulators. Further, the dither may be added at any point in the modulator with suitable filtering of the dither. The transfer function of the filter (11₁ ... 11 N+1 ) is proportional to the noise shaping transfer function of the modulator between the point of addition of the dither and the input to the quantizer.

Abstract: A drill guide (10) is disclosed in which a cylindrical guide tube (16) is secured to a handle (12) so that it may not be easily longitudinally moved in either direction without the user engaging a thumb activated locking mechanism. The cylindrical guide tube passes through a conically tapered cylindrical bore (31) within the drill guide handle and a similarly tapered split collet (32) is interposed concentrically between the exterior of the cylindrical guide tube and the interior of the bore. The collet is provided with a plurality of longitudinally extending lobes which are sufficiently resilient that movement of the collet to its proximal-most position causes the lobes to squeeze inwardly against the cylindrical guide tube. Frictional engagement between the collet lobes and the guide tube prevents the latter from moving until the collet is moved distally to release pressure on the lobes. The collet is normally biased proximally by a leaf spring (42,48) attached to the drill guide handle and a thumb activated lever (40) is provided to move the leaf spring distally to release pressure on the lobes and unlock the cylindrical guide tube.

Abstract: A transmitter (2) is arranged on an acoustic drum to transform wave motions generated by hits on the drumhead (10) in electrical signals. The transmitter (2) comprises a vibration sensitive body (8) designed to be elastically forced against the drumhead (10). According to a first aspect on the invention the vibration sensitive body (8) has got an oblong shape (L:W) for detection of wave motions of a predetermined direction and within a predetermined frequency range. Another aspect on the invention is to avoid the risk of mechanical damages to the vibration sensitive body (8) as well as to emphasize the ability to detect the wave motions in the drumhead (10). This is implemented by a holder (3) being fixable to the edge (5) of the drum rim (6). The holder (3) includes an elastic spring device (12, 13) carrying the vibration sensitive body (8). Within the L-shaped holder (3) there are conductors (15) electrically connecting the vibration sensitive body (8) with a connector (16) incorporated with the holder (3).

Title: High temperature superconducting magnetic bearings.
Inventor: MCMICHAEL CHASE KENYON
IPC: F16C32/04
Filed: 1991-12-04
Abstract: A magnetic bearing having a rotatable member and a stationary member on one of which is mounted a superconductor while on the other is mounted a set of permanent magnets or electromagnets arranged as a quadrupole or multiple dipoles. The magnetic member, which is in the form of a dipole, a quadrupole, or other multiple dipole, such as an octopole, is positioned to enable the magnetic fields generated by the permanent magnets to interact with the superconducting material and to confine the shaft in all directions in the desired location. The bearing systems can be used as either a thrust bearing or as a journal bearing, or as both. Each dipole may be twinned to reduce magnetic field asymmetry and reduce energy dissipation upon rotation. The superconductor may be laminated, and/or additional magnets may be located outside the superconductor in order to increase the bearing stiffness and rigidity.
