Abstract: A battery pack that includes a cell array, a set of first cells of the cell array disposed within the battery pack as one or more first groups of electrically coupled cells, and a set of second cells of the cell array disposed within the module housing as one or more second groups of electrically coupled cells. The set of first cells have a first chemistry, the set of second cells have a second chemistry different from the first chemistry, and the set of first cells are interleaved with the set of second cells inside the battery pack.

Abstract: Secure handsfree proximity-based access control is provided by a system that includes system devices located near different secured resources. Each system device may broadcast a changing unique identifier to user devices in wireless range of the system device. The system may also include an application that runs on each user device, and that obtains a signal strength measurement in response to receiving or detecting a current identifier advertised from a system device. The application may request access to a secured resource over one or more available wireless networks in response to satisfying the signal strength threshold. The system may include an access control unit that authorizes access to the secured resource based on the earliest arriving request, and further based on an identifier of the request matching to the current identifier, and the current identifier not having been previously used to obtain access to the secured resource.

Abstract: One or more beaconing devices transmit synchronized changing beacons. The changing beacons trigger execution of an application that is installed but closed or not running on a mobile device, that is in wireless beaconing range of a beaconing device, and that has registered the changing beacons with the mobile device operating system (“OS”) to trigger execution of the application upon receipt of the changing beacons. The changing beacons also keep the executing application running by resetting OS policies for closing the application when it is running with the mobile device in a locked or standby state. The application may perform different procedures and different times with the beaconing device or other devices including authorizing access to a secured resource when the mobile device is far away from the beaconing device, and confirming intent to access the secured resource when the mobile device is close to the beaconing device.

Abstract: The solution is directed to access control systems and verifying proximity of a user to an access point that the user is wirelessly requesting access to. The proximity verification is based on placing proximity hubs adjacent to the different access points. Each proximity hub advertises a different unique identifier that changes periodically over a short-range wireless network and can be detected with a mobile device if the mobile device is physically within a short distance from the proximity hub. The unique identifier changes based on a rolling code. A user is permitted access to a restricted access point in response to the mobile device sending over a different long-range wireless network, the unique identifier advertised from a proximity hub adjacent to a desired access point and user access credentials authenticating access privileges of the user to the desired access point.

Abstract: Secure handsfree two-stage access control is provided via a first stage that is performed when a mobile device is within a first distance from an access control reader, and a second stage that is performed when the mobile device is within a second distance from the reader, wherein the second distance is less than the first distance. Performing the first stage includes establishing a secure connection between the mobile device and the reader, and authorizing access for the mobile device to a secured resource. Performing the second stage includes providing access to the secured resource when the mobile device has been authorized to access the secured resource during the first stage, and the mobile device enters within the second distance from the reader. The second stage may be triggered in response to the reader detecting a user gesture or action.
