Publication number: 20240109443Abstract: The present invention discloses methods and systems for scheduling and distributing power for electric vehicle chargers, through enabling and disabling a plurality of relays at a system. One of the criteria to allow an authenticated user to use an electric vehicle charger is whether there is enough electricity capacity. When the user is allowed to use a scheduled electric vehicle charger, its location is then sent to the user. Alert messages can be generated if charging does not begin within a first time limit and the cancellation of a reservation will take place if the second time limit is reached.Type: ApplicationFiled: December 13, 2023Publication date: April 4, 2024Applicant: Pismo Labs Technology LimitedInventors: Alex Wing Hong CHAN, Ming Pui CHONG, King Shan LAM, Chi Leong KWOK

Patent number: 8703073Abstract: A lithographically structured device has an actuation layer and a control layer operatively connected to the actuation layer. The actuation layer includes a stress layer and a neutral layer that is constructed of materials and with a structure such that it stores torsional energy upon being constructed. The control layer is constructed to maintain the actuation layer substantially in a first configuration in a local environmental condition and is responsive to a change in the local environmental condition such that it permits a release of stored torsional energy to cause a change in a structural configuration of the lithographically structured device to a second configuration, the control layer thereby providing a trigger mechanism. The lithographically structured device has a maximum dimension that is less than about 10 mm when it is in the second configuration.Type: GrantFiled: March 6, 2009Date of Patent: April 22, 2014Assignee: The Johns Hopkins UniversityInventors: David Hugo Gracias, Timothy Gar-Ming Leong
