Title: Method for rinsing fabric articles in a vertical axis washer
Inventor: VAN NEWENHIZEN JEANNE C
IPC: D06F35/00
Filed: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides a method of rinsing fabric in a washer having a wash chamber rotatable about a vertical axis.      Water is added to the wash chamber while rotating the wash chamber about its vertical axis a number of resolutions sufficient to cause the fabric, rinse water and wash chamber to rotate at approximately the same speed.  The wash chamber is periodically decelerated to cause the fabric and rinse water to move relative to the wash chamber due to rotational inertia of the fabric and rinse water.  The fabric is caused to tumble within the wash chamber as the wash chamber decelerates by impinging the fabric on structures in the wash chamber as the fabric is moving relative to the wash chamber.  A spray of rinse water is directed onto the fabric during a first period of time as the fabric is rotating with and tumbling in the wash chamber.  The rinse water is then drained from the wash chamber.  Finally, the rinse water is removed from the fabric by spinning and draining the wash chamber.

Patent CA-2094462-A1 (CA)
Inventor: LIU QINGLI
IPC: H03M13/41
Filed: 1993-04-20
Abstract: ABSTRACT     A maximum likelihood decoding system includes a branch metric processor which calculates only one of four branch metrics associated with branches leading to two consecutive states sj and Sj+1, where j is even.  The system determines the remaining three metrics by producing a second branch metric by manipulating the first branch metric using simple binary operations and assigns the first and second metrics to the second and first branches, respectively, leading to the odd state.  The system next retrieves associated path metrics from a path metric memory which stores the information in locations accessed by addresses related to identifiers associated with the branch initial states.  After the system selects a surviving path for each end state, it stores in a path memory location associated with the end state information identifying the previous state on the surviving path.  Thereafter, during trace back, the system uses the identifier of a known end state to address the path memory and retrieve the information identifying a previous state on the path.  The system assigns data values to the branches of the most likely path as soon as it identifies the states on the path, since all branches leading to an even state are associated with a "ZERO" data bit and all branches leading to an odd state are associated with a "ONE" data bit.

Title: Modular low air loss patient support system and methods for automatic patient turning and pressure point relief
Inventor: THOMAS JAMES M C
IPC: A61G7/00
Filed: 1990-01-19
Abstract: A low air loss patient support system includes a plurality of identical multi-chambered inflatable sacks. A restrictive flow hole connects two adjacent chambers disposed predominately to one side of the centerline of the sack, and each side is separately pressurizable under the control of a microprocessor and a plurality of pressure control valves with pressure transducers and a plurality of flow diverter valves for switching between different modes of configuring the manner in which the sacks are pressurized.  The system includes a modular manifold for mounting the pressure control valves, and a modular support member for mounting the sacks via quick-disconnect couplings and having air flow channels defined therethrough.  The support system effects a method of rotating or tilting the patient that depres-surizes one side of the sacks while increasing the pressurization of the opposite side of the sacks.  The end chamber of the depressurizing side of the sacks remains inflated while the intermediate chamber of the depressurizing side of the sacks becomes progressively deflated during depressurization to permit the end chamber to restrain the patient from sliding off the sacks during tilting.  The support system permits practicing the method of relieving pressure points between the patient and the sacks while elevating the head and chest of the patient by reconfiguring the diverter valves to connect alternating sacks at the same pressure and periodically decreasing the pressure in one group of sacks while increasing the pressure in the other group of sacks to alternately relieve the pressure of the weight of the patient between the two different groups of sacks depending upon which group is depres-surizing and which group is being increased in pressure.
