  • Publication number: 20240070558
    Abstract: Methods, non-transitory computer readable media, and reservation management devices are disclosed that obtain workspace parameter(s) from a client device after authenticating a user of the client device. User geolocations are determined for the authenticated user and registered user(s) identified by the authenticated user. Workspaces are filtered based on a correlation of the user geolocations and workspace geolocations for the workspaces to identify a subset of the workspaces. The workspaces are determined to satisfy the workspace parameter(s) based on workspace data for the workspaces. A selection of one of the subset of the workspaces is received from the authenticated user. Availability data for the one of the subset of the workspaces is updated based on a time window input by the authenticated user. A digital calendar invitation is then generated and provided to the client device and/or other client device(s) associated with one or more of the registered user(s).

  • Patent number: 10825415
    Abstract: A time controller is able to convert and present the LCD display of gray levels within images with a brightness equal to that within the original images. The time controller alternates in operation between first and second modes of gamma correction, each for a specified time duration. In the first correction mode, the time controller corrects the original gray levels in a correction-positive manner and outputs first correction gray levels. In the second correction mode, the time controller corrects the original gray levels in a correction-negative manner, and outputs the second correction gray levels. The first correction gray level is equal to or larger than the second correction gray level, to correspond with original gray levels.
