Abstract: A mobile tag reader that may be configured to wirelessly communicate with a security tag is provided. The mobile tag reader may include a position estimator, which includes processing circuitry configured to receive information indicative of at least a first read event associated with a first antenna beam pattern and a second read event associated with a second antenna beam pattern emitted by the mobile tag reader. The processing circuitry may be further configured to identify an overlap area between at least the first antenna beam pattern and the second antenna beam pattern. The processing circuitry may be further configured to determine an estimated location of the security tag based on the overlap area.

Abstract: A mobile tag reader that may be configured to wirelessly communicate with a security tag is provided. The mobile tag reader may include processing circuitry. The processing circuitry may be configured to determine a position of the mobile tag reader in the monitoring environment. The processing circuitry may be further configured to determine a position of the security tag in the monitoring environment based on the mobile tag reader position. The processing circuitry may be further configured to in response to a loss of confidence in the mobile tag reader position, execute a location estimating routine to determine an estimated mobile tag reader position.

Abstract: A mobile tag reader that may be configured to wirelessly communicate with a security tag is provided. The mobile tag reader may include a position estimator, which includes processing circuitry configured to receive information indicative of a position of the mobile tag reader. The processing circuitry may be further configured to receive information indicative of location coordinates of the security tag based on wireless communications between the mobile tag reader and the security tag, The processing circuitry may be further configured to calculate an estimated position of the security tag based on information indicative of the position of the mobile tag reader and the information indicative of the location coordinates of the security tag.

Abstract: An adaptor for connecting a luminaire to a track receptacle is disclosed. The track receptacle has retaining flanges along its bottom edges and an insulator assembly adjacent the top. The insulator assembly mounts parallel electrical conductors in the top of the track receptacle and also defines parallel guide channels. The adaptor includes a body having a lid. The lid includes retainers for mating with the retaining flanges. A pair of spring biased electrical contacts extend upwardly from a contact housing mounted in the body and extending through the lid. The housing includes a pair of guide members which are rotationally biased to an aligned position for insertion into the track receptacle.
