Title: Engine and method for exhaust aftertreatment
Inventor: Spencer Huhn
IPC: F02M61/04
Filed: 2020-04-14
Abstract: Disclosed is a method of increasing parasitic load on an internal combustion engine 12 which includes injecting a fuel into a combustion chamber of an active cylinder 16 of the internal combustion engine 12, combusting the injected fuel in the combustion chamber of the active cylinder 16 and determining that increasing a temperature of an exhaust aftertreatment device 68, 70, 72 is required. The method includes increasing a parasitic load on the internal combustion engine 12 by deactivating a cylinder 16, wherein no fuel is injected in the deactivated cylinder 16 for a combustion cycle of the internal combustion engine 12 and further increasing the parasitic load by pulsing a spill valve member 142 of a spill valve 140 of a fuel injector 18 in the deactivated cylinder 16 between a fully closed position and an at least partially open position. Pulsing the spill valve controls the fuel pressure in the injector and increasing the pressure within the fuel injector may increase the parasitic load on an engine by increasing the pressure against which fuel is pumped.

Title: Speaker system and network control method thereof
Inventor: TAO YUAN
IPC: H04W76/10
Filed: 2020-08-12
Abstract: In a speaker system, the master speaker establishes a connection with a slave speaker and determines a target speaker (connected to a server). It then obtains the address of the server from the target speaker and sends this to a control terminal (such as a mobile phone). The control terminal connects to the server and sends control instructions to the master speaker via the server. A control instruction may be a command to adjust an audio parameter such as volume or tone. The user may also make audio adjustments at the master speaker which are then uploaded to the server and forwarded to the slave speakers. The scheme enables centralised control of the speaker system.

Title: Shunt current regulator for downhole devices
Inventor: TROND HAGEN
IPC: H02M1/00
Filed: 2019-06-28
Abstract: A shunt current regulator can be used to maintain current levels at downhole device on a tubing encapsulated cable and improve communication speed between the surface and downhole devices. The shunt current regulator reduces the current noise on the tubing encapsulated cable allowing for higher bitrate transfer. In some aspects, a sensing element monitors the current drawn and generates a sense signal. In other aspects, a compensation signal is generated from the sense signal. The compensation signal may be used as input to control a transistor to regulate the current drawn from the tubing encapsulated cable. The transistor can dissipate power to stabilize the current drawn or provide compensation current to increase the current drawn.
