iHome Alarm Clock connected to a 4th-generation iPod. Created in 2005, the iHome division produces docking stations, headphones, smart home devices, and other accessories. iHome speakers are able to stream music over Apple AirPlay, Bluetooth, as well as via a wired connection. In addition to playing music wirelessly, some systems can act as a ...
In a time-slot interchange (TSI) switch, two memory accesses are required for each connection (one to read and one to store). Let T be the time to access the memory. Therefore, for a connection, 2T time will be taken to access the memory. If there are n connections and t is the operation time for n lines, then t=2nT which gives n=t/2T
A simple 24-hour cyclical electromechanical time switch with a French CEE 7/5 socket. A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall ...
Apple Home is a smart home platform developed by Apple Inc. that lets users configure, communicate with and control smart appliances using Apple devices. Apple Home communicates with devices using HomeKit, the software framework and communication protocol developed by Apple, and the open Matter standard. [1]
A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.
At one end is the manual gating of clocks by software, where a driver enables or disables the various clocks used by a given idle controller. On the other end is automatic clock gating, where the hardware can be told to detect whether there is any work to do, and turn off a given clock if it is not needed.

Type of clock A traditional wind-up (key-wound), mechanical spring-powered alarm clock An alarm clock or alarm is a clock that is designed to alert an individual or group of people at a specified time. The primary function of these clocks is to awaken people from their night's sleep or ...
In addition to clock skew due to static differences in the clock latency from the clock source to each clocked register, no clock signal is perfectly periodic, so that the clock period or clock cycle time varies even at a single component, and this variation is known as clock jitter. At a particular point in a clock distribution network, jitter ...
