    Abstract: A remote control system includes an object detection unit, an object determination unit, and a static gesture processing unit. The object detection unit detects an object corresponding to an operator according to a depth image including the operator and a face detection result corresponding to the operator. The object determination unit utilizes a combination of a gesture database, a color image of the object, and a two-dimensional image corresponding to the depth map to determine a gesture formed by the object when the operator moves the object to a predetermined position. The operator moves the object to the predetermined position and pulls the object after the operator moves the object to the predetermined position within a first predetermined period. The static gesture processing unit generates a first control command to control an electronic device according to at least one static gesture determined by the object determination unit.

  • Publication number: 20200267869
    Abstract: An enclosure for installation in a server rack has front panel access to multiple release mechanisms. The front panel access allows separate and safe dual tasking of both hot and cold swaps. A hot swap mechanism allows a sled to be ejected while retaining a connection to electrical power. A separate cold swap mechanism releases the sled and also disconnects the electrical connection. When the hot swap mechanism is engaged or enabled, one or more mechanical linkages operate to lock out access to the cold swap mechanism. When the cold swap mechanism is engaged or enabled, the mechanical linkages interferes or blocks manual operation of the hot swap mechanism. Both the hot swap mechanism and the cold swap mechanism thus cannot be inadvertently and/or simultaneously performed.
