A drive-condition setting device applied to an optical scanning apparatus having a fiber and an actuator that vibrates a distal end of the fiber, the drive-condition setting device detects a scan pattern of the illumination light output from the fiber, measures resonance frequencies in the x direction and the y direction of the fiber, sets a drive frequency and a drive voltage based on the resonance frequencies such that conditional expressions below are satisfied: when fx>fy, fd<fy and VxVy (1) or fd>fx and VxVy (2), and when fxfy, fd<fx and VxVy (3) or fd>fy and VxVy (4) where fd denotes the drive frequency, Vx denotes a maximum voltage of a X direction drive signal, and Vy denotes a maximum voltage of a y direction drive signal.

A mechanism for transparent (or non-disruptive) virtual tape engines restart. Specifically, the disclosed mechanism entails preserving a pre-restart state prior to restarting a virtual tape engine, followed by restoring the pre-restart state after the restarting in order to achieve transparency.

At a high level, embodiments of the invention relate to augmenting video data with presence data derived from one or more proximity tags. More specifically, embodiments of the invention generate forensically authenticated recordings linking video imagery to the presence of specific objects in or near the recording. One embodiment of the invention includes video recording system comprising a camera, a wireless proximity tag reader, a storage memory and control circuitry operable to receive image data from the camera receive a proximity tag identifier identifying a proximity tag from the proximity tag reader, and store an encoded frame containing the image data and the proximity tag identity in the storage memory.

A data storage library is described that protects against a malware attack by providing a scheduled write window of time where archive data can be written to tape cartridges in the tape library on behalf of a client. At times outside of the write window, the tape library is disabled from writing any archive data to any of the tape cartridges in the tape library. Accordingly, the tape library is protected from a malicious entity attempting to download malware to tape cartridges in the tape library outside of the designated write windows. The tape library is configured to provide or otherwise read archived data from a tape cartridge both in the write window and outside of the write window.

A multiple recording device management system including an intermediate multiple recording device managing apparatus, a vehicle recording device mounted in a police vehicle and synced to the managing apparatus, and a personal recording device carried by a police officer and wirelessly synced to the managing apparatus. The managing apparatus is operable to detect when the vehicle recording device, personal recording device, or any other synced device in range has begun recording and to transmit a communication signal to any synced recording device in range indicating that the recording device should begin recording and to further transmit a time stamp to synced recording devices for corroborating recorded data.

Embodiments of the invention relate to a portable digital video system sized to be worn on the user's body and equipped with a plurality of lens assemblies for recording video in a plurality of directions. In one embodiment, the invention includes a camera unit comprising a first lens assembly, a second lens assembly, a first housing containing the first lens assembly and the second lens assembly, a battery unit, a first storage memory, controller circuitry operable to receive video data from the first lens assembly and the second lens assembly and store the video data in the first storage memory, and a second housing containing the battery unit and attached via a cable to the first housing unit. In some embodiments, the system is equipped with both volatile and non-volatile memory for continuous recording with permanent storage of key video segments.
