A projection apparatus and a control method thereof are provided. The projection apparatus includes a processor, a sensor, and a projection module. When a command corresponding to a standby mode is received, the processor sets the projection apparatus to a first sub-standby mode. The sensor is enabled to sense whether there is a living object located in a sensing area outside the projection apparatus. The standby mode is maintained as the first sub-standby mode in response to sensing that the living object is not in the sensing area. The standby mode is set to be switched to a second sub-standby mode in response to sensing that the living object is in the sensing area. A maximum power consumption of the first sub-standby mode is less than a maximum power consumption of the second sub-standby mode. In the first and second sub-standby modes, the projection module is not enabled.

Projection apparatus and control method thereof

Disclosed is a serial test circuit for controllable Chiplets, which belongs to the technical field of test or measurement of semiconductor devices during manufacturing or processing. The test circuit includes a master control test module, a slave control test module, a clock controlling module and an outputting module. The master control test module is composed of a test access port module, a segment insertion bit module and a test data register module. The test controlling signal is generated by the master control test module, and the test inputting signals of the slave Chiplets are respectively controlled by the slave control test module after receiving the test controlling signal. At the same time, the test controlling signal is inputted to the clock controlling module to obtain the clock signals of the slave Chiplets. The output signal of the test outputting module is determined by the test controlling signal.

Serial test circuit for controllable Chiplets

The present disclosure relates to the field of design for testability of super-large-scale integrated circuits, and discloses a flexible configurable module (FCM) based chiplet test circuit. The core structure of the circuit is located at an interposer. The test circuit includes FCMs, a control signal configuration module and a test state control module, where the FCM adopts a two-way skew-symmetric structure to implement data transmission in the horizontal direction and the vertical direction; the control signal configuration module is connected to control signals of all the FCMs, so as to control the data transmission directions as well as switch on and switch off states of all the FCMs; and the test state control module controls the shift and update operations of data inside the FCMs and the control signal configuration module.

FCM based chiplet test circuit

A quick connection mechanism includes a truncated-cone-shaped quick release plate, a base, and a locking structure. A tapered clamping groove is provided in a larger bottom surface of the quick release plate. A sliding groove is provided in the base, and the quick release plate is clamped in the sliding groove. The locking structure is configured to fix the quick release plate that enters the sliding groove. The locking structure includes a rotating shaft, a locking arm rotatably provided on the rotating shaft, and a first elastic member connected to the locking arm and configured to apply, to the locking arm, a force in a direction for locking the quick release plate. One end of the locking arm abuts against an inner side wall of the clamping groove and is configured to enable locking of the quick release plate in the sliding groove by the abutment.
