Abstract: An electrical outlet assembly includes a sub-faceplate having a front surface and first set of contacts position on the front surface. An outer faceplate includes an outer surface and an inner surface, the inner surface having a second set of contacts. The outer faceplate is releasably connected to the sub-faceplate so that the first set of contacts connect to the second set of contacts.

Abstract: A portable device charging unit includes a battery, a base supporting the battery and including an inductive charging surface, and at least one retainer for selectively securing an electronic device in engagement against the inductive charging surface. In addition, a system may be provided for storing and dispensing one or more device charging units.

Abstract: A charging system includes a first charging portion and a second charging portion. The first charging portion includes at least one first connector and at least one first interface for charging a connected device. The first charging portion is configured to receive electrical current from a power source. The second charging portion includes at least one second connector and at least one second interface for charging a connected device. The at least one first connector is removably coupled to the at least one second connector, thereby removably coupling the second charging portion to the first charging portion to facilitate transmission of electrical current between the first charging portion and the second charging portion.

Abstract: One embodiment provides a non-contact power transmitter device including a sealed housing provided at least partially within a surface, and a transmitter coil within the sealed housing configured to inductively transfer power to a power receiver device. The power transmitter device also includes a transmitter control unit coupled to the transmitter coil, a transceiver configured to communicate with the power receiver device, and an electronic processor coupled to the transmitter control unit and the transceiver. The electronic processor is configured to establish, using the transceiver, communication with the power receiver device, and negotiate power transfer requirements between the power transmitter device and the power receiver device. The electronic processor is also configured to control the transmitter coil unit to transfer power to the power receiver device.

Abstract: A device charging system application to track one or more batteries configured to supply power to at least one load device and a central charging station in communication with the battery and including a transceiver and an electronic processor configured to define a virtual boundary within an area proximate to the central charging station, determine a proximate location of the battery, determine, based the location of the battery, whether the battery is within the virtual boundary, and transmit a command to the battery causing the battery to stop supplying power to the load device when the battery is not within the virtual boundary.

Abstract: A battery management system including a battery center and a controller. The battery center includes one or more battery receptacle. The battery center is configured to: receive one or more batteries, identify one or more batteries, and charge one or more batteries. The controller includes a memory and an electronic processor. The controller is configured to: receive, from the battery center, a status of one or more batteries, receive, from a user, an unlock request, and output, to the battery center, an unlock command. Wherein, the battery center unlocks one or more batteries from the one or more battery receptacle upon receiving the unlock command.

Abstract: A device charging system including a battery module and a central charging station. The battery module is configured to supply a type of power to at least one load device. The central charging station is in communication with the battery module. The central charging station includes an electronic processor configured to define a virtual boundary, determine a location of the battery module, determine, based the location of the battery module, whether the battery module is within the virtual boundary, and transmit a command to the battery module causing the battery module to stop supplying power to the load device when the battery module is not within the virtual boundary.

Abstract: A data storage subsystem which reduces seek time, by defining a logical storage space wherein part of the logical storage space is defined to correspond to a primary storage space of a first physical data storage device, and correspond to a secondary storage space of a second physical data storage device, and another part of the logical storage space is defined to correspond to a primary storage space of the second physical data storage device, and correspond to a secondary storage space of the first physical data storage device. For hard disk drives having an arm assembly with a read/write head, the average seek distance for both drives reduced, since the pivoting arm assembly need not travel as far to reach each physical storage address within a primary storage area. The invention may additionally take advantage of geometric or other aspects of the storage devices which result in some portion of the device having a faster access time that another portion.

Abstract: The invention is a horizontally operated door barrier which presents virtually an impenetrable doorway barrier while maintaining ease of personnel access through the portal. The invention consists of a movable vertical spool upon which is wrapped a material or screen for covering the doorway. The spool moves laterally across the doorway, rolling or unrolling the screen wrapped thereon, thereby uncovering or covering the doorway. The barrier can be used to prevent passage of insects, moisture, heat, dust and like environments.
