Title: Cleaning appliance
Inventor: CHRISTOPHER GRAHAM VINCENT
IPC: A61C17/36
Filed: 2016-09-26
Abstract: A pump assembly 48 for a dental cleaning appliance includes a reciprocating piston 84 or diaphragm which is driven in a fluid chamber 82. Permanent magnets 86,98 couple the piston 84 and the drive 96, enabling the piston 84 to be retracted linearly against the return force of a spring 94 to draw fluid into the fluid chamber until an annular drive plate 92 extending about a connecting rod 90 between the piston 84 and the magnet 86 hits a first, selectively movable stop 102, preventing further withdrawal of the piston 84, causing the magnets to pull apart and decouple, converting potential energy into kinetic energy as the spring 94 returns the piston 84 and forces a burst of fluid from the fluid chamber 82. The volume of fluid dispensed may be increased by moving the stop 102 into a stowed position, allowing the drive plate to retract further until it hits a second stop. The pump may also be run in a purge mode.

Title: Dynamic scaling of channel state information
Inventor: FILIPE CARVALHO
IPC: H04L27/38
Filed: 2018-06-29
Abstract: A demodulator 500 comprising a soft decision error corrector 114 decodes data symbols of a received signal based on channel state information (CSI) values. A CSI scaling module 502 applies a scaling factor to CSI values, and the scaled CSI values are provided to the soft decision error corrector. The performance of the soft decision error corrector is monitored, and if the performance is below a predetermined level, a new CSI scaling factor is selected based on the performance. The new CSI scaling factor is used to generate new modified CSI values. A plurality of scaling factors may be compared to select the multiplying factor that provides the best performance. The soft decision error corrector may comprise a low-density parity check (LDPC) decoder 116, the performance based on the number of LDPC iterations required to remove errors in a forward error correction block. Different methods of selecting a new CSI scaling factor may be based on whether the current scaling factor is close or far from achieving threshold performance. The plurality of scaling factors may be widely spaced, or fine CSI adjustment factors may be used to tune the current CSI scaling value.
