摘要： A communication and security device for a portable computer having an interface for connecting the security device to a host device to enable the security device to control encryption and decryption of data communication between a processor of the host device and a data storage of the host device. Examples include a security device with data storage for storing an encryption key for the encryption and decryption of the data communication, a security processor coupled to the interface and to the data storage for controlling the data communication by use of the encryption key, and a wide area communication interface configured for secure communication with a remote device. The security processor may be configured to control the data communication between the processor of the host device and the data storage of the host device based on the secure communication.

摘要： A tracking device (150) for tracking an asset (110) at a facility is described herein. The tracking device comprises a communication interface (120) configured to communicate with at least one beacon (101-1, 101-2, 101-n) in proximity to the tracking device and an altitude sensor (125). The tracking device is configured to receive, via the communication interface, at least one signal from the at least one beacon, receive, via the altitude sensor, altitude information. The tracking device is configured to transmit, for use in tracking the asset at the facility, information based on the at least one signal and the altitude information.
