Title: Laser surgical device and method of its use
Inventor: ODINTSOV OLEG D
IPC: A61B18/20
Filed: 1996-03-05
Abstract: A laser surgical device (10) for vaporization of a living tissue consists of an operating laser assembly (22, 24, 26, 28, 30, 32, 34), a detecting an arrangement (48), and a control unit (14). The operating laser assembly generates an operating beam having a predetermined wavelength corresponding to a peak absorption wavelength of water. The detecting arrangement is adopted for detecting a condition of an operated living tissue by receiving and reviewing a signal reflected from the operated living tissue so as to produce a control signal. The control unit controls characteristics of the operating beam based on the control signal, so that the depth of vaporization of the living tissue does not exceed 15 microns to 20 microns.

Title: Conversion of a pcm signal into a upwm signal
Inventor: RISBO LARS
IPC: H03M1/82
Filed: 1997-03-26
Abstract: To correct non-linearity and noise in the conversion of a pulse code modulated signal (PCM) into a uniform pulse width modulated signal (UPWM), a model is made of the known non-linearity in the conversion by dividing a plurality of non-linearity components in the model, where the polynomial components are separately weighted with filter coefficients. The model is used as a basis for the construction of a filter of the Hammerstein type whose non-linear parts consist of a division of the PCM signal into a plurality of powers, and whose linear parts are approximated by means of the model made. With the circuit of the invention it is now possible to construct a purely digital amplifier which has a great efficiency, low weight, etc.

Patent CA-2280720-A1 (CA)
Inventor: OSTENDORFF ERIC CHARLES
IPC: A63H17/36
Filed: 1998-05-04
Abstract: A chassis (16) supports a toy vehicle body (11) and a pair of front wheels (14, 15) together with a pair of rear wheels (12, 13). A dual motor differential drive mechanism provides independent differential steering and propulsion of the vehicle through remote control of the rear wheels. An integral steering caster (51) supporting both front wheels in a common caster apparatus is pivotally supported by a single forwardly positioned pivot (50) between the chassis and the caster. The pivoting action of the common caster in response to vehicle turning moves the inner one of the front wheels rearwardly while moving the outer one of the front wheels in a turn forwardly. This pivotal movement is accomplished with a simple, low cost steering caster and provides a heightened appearance and performance effect.

Abstract: The apparatus of the present invention stimulates the muscles of a seat occupant. The invention includes a flexible supporting element (12) adapted to be coupled to a seat for movement relative thereto and driving means (24) for automatically and repeatedly moving the flexible supporting element (12) through an adjustment cycle. The adjustment cycle includes a plurality of first incremental movements (56) in a first direction followed by a plurality of second incremental movements (62) in a second direction.

The method of the present invention relieves muscle fatigue in a seat occupant by incrementally adjusting the curvature of the supporting element and generally includes the steps of placing a supporting element in a first position operatively engaging a muscle of the seat occupant wherein the first position defines a first degree of curvature of the supporting element.  The method further includes automatically adjusting the curvature of the supporting element according to an adjustment cycle that includes maintaining the first degree of curvature for a first time period, increasing the degree of curvature a first amount after the first time period to define a second degree of curvature, maintaining the second degree of curvature for a second time period, and decreasing the degree of curvature of the supporting element a second amount after the second time period to define a third degree of curvature wherein the first time period is equal to the second time period.
