Patent EP-0343912-A2 (EP)
Inventor: WATKINS JONATHAN
IPC: A61H33/00
Filed: 1989-05-23
Abstract: A unit for use in a tub (10) or spa to provide a dry hydro-massage of the neck and shoulders. The units (12) mounts to the tub edge (14) and includes a diaphragm (36) which sealingly covers a discharge jet (26) such that the fluid will flex the diaphragm into massaging relationship with the user's body. The water is exhausted into the tub through a secondary port (46) below the water line such that dry hydro-therapy is provided by the unit. The inflation of the diaphragm is controlled by pressure regulating ports (42) formed within a housing (16) of the unit to control the exhaust of fluid from the jet chamber. In one embodiment, the ports are variable to vary the inflation pressure of the diaphragm. With the unit mounted to the tub the user may remain seated within the spa while the unit provides a dry hydro-massage of the neck and upper back normally positioned above the water line. To provide increased freedom of application of the hydro-massage, the unit may be incorporated into a telescopingly adjustable assembly associated with the tub wall or a hand-held assembly.

Title: Low emissions wood burning stove
Inventor: HAZARD GARY MEAD
IPC: F23G7/07
Filed: 1989-07-19
Abstract: A wood burning stove incorporates a catalytic cell for reducing exhaust emissions from the stove. A pair of heat shields are spaced from opposing surfaces of a combustor to exchange thermal radiation with the combustor. The combustor is oriented at an acute angle to enhance the combustor life. One of the heat shields also functions as a deflector for deflecting exhaust toward the combustor. A secondary air unit supplies secondary air to the vicinity of the combustor. A dynamic grate assembly is employed to prevent under firing of the firebox.

Abstract: To separate high-molecular DNA strands, an electrophoresis system includes first means for changing the direction of an electric field within an electrophoresis separating unit at a first frequency having a period of no more than 20 seconds and second means for changing the electric field in another manner at a second frequency at least twice as high as the said first frequency. In one embodiment, the field strength in the direction of overall migration is selected so that, considering the DNA size and gel density, the leading segment of DNA to the first corner is sufficiently small so that excess friction forces due to bunching does not cause excessive band spreading. The field strength is selected so that the electric field is reduced until the changing of the electric field at the second frequency keeps the bunching effect to a sufficiently low level to not seriously interfere with the separation.

Abstract: The aim is to effect the reception of a binary digital signal, which may also have phase shifts, with the aid of a delivered clock pulse, which has an arbitrary phase angle with respect to the digital signal and whose frequency can deviate somewhat from the bit sequence frequency of the digital signal. 
<??>The digital signal (D1) is delayed in a delay line (2-6) in such a way that a sequence of digital signals (D1-D6) having the same phase spacings is produced, from the rising and falling edges of which pulses (I11-I16) are derived. Interrogation pulses (I41), which are combined with the pulses (I11-I16) - to the extent that they are present - in assigned AND gates (14-19), are derived from the rising or falling edges of a clock pulse (T). Each output signal of one of these AND gates switches through the associated digital signal (D1-D6) in a downstream further AND gate (20-25) to an OR gate (26). The output signal (Dx) of this OR gate (26) is scanned in a D flipflop (32) by means of delayed interrogation pulses (I42) in such a way that the scanning is performed approximately one quarter clock pulse period after the effective edge of this output signal (Dx). 
<??>This arrangement can be used in ISDN broadband switching systems.

Abstract: a method for recapturing a satellite at the highest elevation angle as quickly as possible with a GPS receiver having a plurality of receiving channels when a state of receiving satellite signals recovers to normal after having been interrupted by obstacles like a tunnel, wherein a search range of satellite signal receiving frequency is divided into a plurality of frequency bands and each of which is assigned to the plurality of receiving channels in a one-to-one relationship, a search frequency of each receiving channel is changed in step wise for searching a satellite signal simultaneously in the receiving channels, and further, by providing a time difference for a step wise change-over timing of the search frequency between receiving channels, a time required for recapturing the satellite is greatly reduced by increasing a chance to lock up one of the receiving channels with the satellite signal receiving frequency, since there are as many chances as a number of receiving channels within one cycle of the step wise search frequency change-over for one receiving channel.

Abstract: Apparatus and method are presented for actuating a passenger restraint system (10) in a passenger vehicle. A sensor (14) senses vehicle deceleration and provides a deceleration signal having a value that varies in accordance with deceleration. A plurality of crash evaluation circuits (EV-1,EV-2,EV-N) each respond to the deceleration signal for evaluating the deceleration signal in accordance with respectively different crash evaluation algorithms. Each evaluation circuit provides a FIRE vote signal when its evaluation of the deceleration signal indicates that the restraint system should be actuated. A crash evaluation expertise circuit is associated with all but one of the plurality of crash evaluation circuits. Each expertise circuit has an expert output circuit (EXP1,EXP2) for providing an expert signal when the expertise circuit determines that its associated evaluation circuit is an expert in evaluating the type of crash condition represented by the deceleration signal. The FIRE vote signals and the expert signals are summed to provide a summation signal having a value dependent on the sum of the signals. The restraint systems is actuated when the value of the summation signal exceeds a threshold level.
