Title: An adaptive loop filter
Inventor: PATRICE ONNO
IPC: H04N19/82
Filed: 2019-12-20
Abstract: A method of controlling an Adaptive Loop Filter (ALF), for filtering an image portion made up of a plurality of blocks, comprises obtaining ALF parameters defining filters applicable to blocks of the image portion 716, 718 and imposing a limit on a maximum number of filters usable for filtering the blocks of the image portion. Information may be obtained indicating a filter identity, selection or change or indicating enabling or disabling of a filter, applicable to a group of blocks within the image portion. Plural alternative filters may be available for at least one ALF class. There may be two or more alternative filter sets, providing respective alternative filters for each of plurality of filter indexes or ALF classes. A limit may be imposed on the maximum number in the sets collectively, or on the maximum number in each set. Such a technique can reduce the memory requirement for ALF filters, which may otherwise become prohibitively high, especially for a hardware decoder.

Title: A lubricant recovery system
Inventor: GLENN VINCK
IPC: F04C29/02
Filed: 2020-06-24
Abstract: A lubricant recovery system for a vacuum pump 12 has a lubricant reservoir 10 and a supply line 14 connected between the reservoir and the vacuum pump. In use, the supply line supplies lubricant to the vacuum pump, and a return line 18 returns a lubricant-air mixture from the vacuum pump to the reservoir. An air filter 26 within the reservoir separates lubricant from the lubricant-air mixture, and a scavenge line 28 connected to a low-pressure region 30 of the vacuum pump returns lubricant collected in the air filter back to the pump. A valve 32 in the scavenge line controls flow between the vacuum pump and the reservoir, and flow control may be dependent upon the pressure at the low-pressure region of the pump, or the pressure within the apparatus connected to the vacuum pump. Control of the fluid flow in the scavenge line can prevent air from the reservoir entering the vacuum pump under conditions of low scavenge oil flow, and therefore enhance the performance of the vacuum pump. A bypass 34 with a throttle 36 may also be included to maintain drainage of the filter under low flow conditions.

Title: Drive circuit for a brushless motor
Inventor: STEPHEN GREETHAM
IPC: H02P27/16
Filed: 2020-12-03
Abstract: Brushless motor drive circuit, comprising: a bridge converter of bidirectional switches SW1-4 connected to the motor’s phase winding 21; and a controller 38 that configures the switches states (Figs.4-8,11). Bidirectional switches have four states (Fig.3): ON, bidirectionally conductive; D1, conductive in a first direction; D2, conductive in a second direction; and OFF, non-conductive. A first configuration configures a first pair of bidirectional switches as ON and second pair as OFF (Fig.7a). A second configuration changes the second pair of switches from the OFF state to a diode state (Fig.7b). A third configuration changes the first pair of bidirectional switches to OFF (Fig.7c). A fourth configuration may change the second pair of bidirectional switches to ON (Fig.7d). A fifth configuration may configure all the switches to a diode state (Fig.15b), from the third configuration, during polarity inversion. A sixth configuration may follow the fifth, and configures the second pair of switches to the OFF state (Fig.15c). A seventh configuration may prevent current from flowing through the phase winding. The controller may switch from the third or sixth to seventh configuration during a zero current. The arrangement removes the need for a rectifier and prevents reversal of current due to back EMF.
