Abstract: A visitation system provides visitation sessions between a resident of a controlled-environment facility and a nonresident, where the nonresident utilizes a personal wireless devices that connects to a wireless access point that may be accessible from a designated visitation area of the facility. A connection request from a personal wireless device of a nonresident is evaluated to determine the personal wireless device is authorized to interface with the visitation system, and whether the nonresident is authorized to communicate with the resident. If authorized, a visitation session between the resident and the nonresident is initiated with the nonresident participating via the personal wireless device. The visitation system may respond to a visitation session request from a registered personal wireless device by sending an access code to the personal wireless device.

In some examples, the processing circuitry is configured to determine whether the biometric input data matches biometric verification data for the first user or the second user, unlock the aircraft in response to determining that the biometric input data matches biometric verification data for the first user or the second user, and activate the aircraft for operation in response to determining that the biometric input data matches biometric verification data for the first user.

Abstract: A determination is made whether read/write is enabled within the tape drive storage unit. In response to determining that read/write is enabled, a determination is made whether an absolute value of a channel offset exceeds a threshold value. In response to determining that the absolute value of the channel offset exceeds a threshold value, a direction of travel of the tape media is determined. In response to determining that the direction of travel of the tape media is a forward direction, a determination is made whether the channel offset is positive. In response to determining that the channel offset is positive, a left cooling device within the tape drive storage unit is powered on. The left cooling device lowers the temperature of a left guide roller and the tape media coming off a left tape storage reel prior to the media passing by a read/write head.

Abstract: A low permeability electrical feed-through involves a laminate structure having alternating conductive and insulating layers with a conductive through-hole positioned therethrough, by which a lower connector pad is electrically connected with an upper connector pad. Such a feed-through may be used at an interface between a hermetically-sealed internal environment, such as in a lighter-than-air gas filled data storage device, and the external environment. An insulating layer is positioned and configured such that an associated horizontal leak path can meet an allowable feed-through leak rate, while the collection of layers is configured such that an associated vertical leak path can meet the feed-through leak rate.

Abstract: A determination is made whether read/write is enabled within the tape drive storage unit. In response to determining that read/write is enabled, a determination is made whether a temperature within the tape drive storage unit exceeds a threshold value. In response to determining that the temperature within the tape drive storage unit exceeds the threshold value, a determination is made of a direction of travel of a tape media within the tape drive storage unit. In response to determining that the direction of travel is a forward direction, a first cooling device is powered on. The first cooling device lowers the temperature of a first guide roller and the tape media coming off a first tape storage reel prior to the tape media passing by a read/write head within the tape drive storage unit.

Abstract: A full-duplex analog relay may comprise an analog uplink relay and an analog downlink relay, and may relay signals between a transmitter and a backscatter node. The spectrum of the downlink signal transmitted by the downlink relay may be different than the spectrum of the uplink signal received by the uplink relay. Filtering may attenuate leakage from the downlink relay to the uplink relay, and vice versa. The uplink relay may create a phase offset that is opposite in sign and substantially equal in magnitude to the phase offset created by the downlink relay. The downlink and uplink relays, taken together, may created a substantially constant net phase offset. The full-duplex relay may be housed in a vehicle that moves, and may be used to determine spatial coordinates of backscatter sources that are located in the relay's environment.

Abstract: The embodiments herein measure the tag to noise ratio (TNR) for a tag on an item (e.g., a package) to determine a location of the item in a warehouse. In one embodiment, the TNR is derived by comparing a measured performance parameter for a tag of interest to the combined measured performance parameters for other tags measured by the same reader or for the same tag when measured by a different RFID reader. The higher the TNR, the greater likelihood the tag is within an area assigned to the reader. In another embodiment, the TNR is derived from comparing the signal strength of a tag as measured by multiple RFID readers. In another example, respective TNR values for a plurality of tags detected by a reader can be compared to determine which tag is being carried by an associate.
