A memory chip includes at least two memory blocks. In a method for controlling power supply for the memory blocks of the memory chip, each memory block receives a command for switching to standby mode. The commands are issued, for example by a processor, separately for each memory block in order to be able to individually place the memory block in standby mode.

11567527 · 2023-01-31 · ·

A circuit comprises a power controller, a real-time clock (RTC) sub-system, and a processing sub-system. The RTC sub-system includes an alarm register storing a predetermined time for a task, and provides an early warning countdown and a scheduled event signal. The processing sub-system includes a processor, a preemptive wakeup circuit, and a component coupled to the processor and configured to execute the task with the processor. The preemptive wakeup circuit comprises a selector logic circuit, a comparator, and a wakeup initiation circuit. The selector logic circuit receives latency values indicative of wakeup times for a clock generator and the component, and outputs a longest wakeup time to the comparator, which indicates when the early warning countdown and the longest wakeup time are equal. The wakeup initiation circuit generates a clock request and disables the sleep mode indicator. The power controller provides a clock signal and wakes the component.

System and method for controlling operation of consumption appliances
11710971 · 2023-07-25 · ·

A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.

The present invention concerns a method for controlling a home-automation facility comprising at least one central control unit (U1, U2) belonging to a home-automation facility; the method being executed by a user terminal (T) and comprising the following steps: selecting (ECTLT1) a first local connection mode (CM1) or a second wide area network connection mode; establishing (ECTLT2) a connection between the user terminal and at least one target unit (U1, U2, Sv), said at least one target unit (U1, U2, Sv) being a central control unit (U1, U2) in the case in which the first local connection mode (CM1) has been selected, and a management unit (Sv) in the case in which the second wide area network connection mode has been selected; sending (ECTLT3) a discovery message (MCTLD1, MCTLD2, MCTLD′) linked with a facility identifier (StID) to at least one target unit (U1, U2, Sv); receiving (ECTLT5, ECTLT7) at least one topology description message originating from the target unit (U1, U2, Sv) comprising a description of a group of devices (DGrSt) attached to the facility identifier (StID).

Display device power mode

The first time a display device is turned on, is turned on after it has been factory reset, or is factory reset, the display device displays a message indicating that in a default and current power mode of the display device, a hardware component of the display device different than display hardware is powered off when the display device enters a low-power state. A user is permitted to have the hardware component remain powered on when the display device enters the low-power state.

Polar coding system for ultra-reliable low latency communication

Systems, methods, and instrumentalities are described herein for supporting CBG-based retransmission with variable CBG size using variable length HARQ-ACK. A WTRU may receive a configuration to use a first table. The first table may be associated with a maximum number of code block groups per transport block (maxCBG/TB). The WTRU may determine a number of HARQ-ACK bits to send for code blocks. The determination may depend on whether an indication is received to switch from the first table to a second table. On a condition that the indication to switch from the first table to the second table is received, the WTRU may send a number of HARQ-ACK bits that is equal to two times the maxCBG/TB. The WTRU may receive a retransmission of a number of code blocks, wherein a code block group size depends on a sent number of HARQ-ACK bits.
