Abstract: An analysis of the scans is performed to determine whether the selected item was moved from the back room to the shelf, then returned from the shelf to the back room. The analysis also determines a re-bin time when the selected product was returned to the back room. An adjustment to the PI is blocked when last PI adjustment time is later than the re-bin time. An adjustment to the PI is also blocked when an audit indicator is received at the interface indicating that the retail store is under an audit. An adjusted PI value is determined when the analysis indicates that the selected item was moved from the back room to the shelf, then returned from the shelf, the adjusted PI value being at least one more than the shelf capacity value.

Abstract: Methods and apparatus consistent with the present disclosure may use a plurality of force sensing devices that allow a computer of an autonomous vehicle (AV) to identify locations within the AV where particular objects reside. These force sensing devices may allow the AV computer to identify how much a particular object weights and identify whether an object has moved based on a location where a particular amount of weight currently resides versus a location where that weight previously resided in the AV. Weight information combined with other sensor data (e.g. camera or LIDAR data) may allow the AV computer to identify whether a particular object is a person or a package. The AV computer may also validate that certain driving rules are enforced, such that persons or packages are being moved safely and correctly in the AV.

Abstract: An expandable intervertebral implant having an upper body portion, a lower body portion opposite the upper body portion. a wedge member connecting the upper body portion to the lower body portion, a nose member having a tapered distal end and a proximal end opposite the distal end, and an actuator disposed between the nose member and the wedge member, for translation of the wedge member along a longitudinal axis of the implant. A pin disposed in a center of the nose member connects to the actuator for centering the nose member with the actuator. Translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.

Abstract: A perpetual inventory (PI) value associated with the selected product and a last PI adjustment time that indicates when the retail store last adjusted the PI value are received. The PI value of the selected product is compared to the back room quantity value of the selected product, and a time when the back room quantity value becomes greater than the PI value for the selected product is determined. An adjustment to the PI of the selected product is blocked when the PI adjustment time is after the time. When the back room quantity value is greater than the PI value and the adjustment to the PI value is unblocked, the PI value is adjusted to be the back room quantity value.
