Abstract: An issue reporting and detection system is discussed. A user can capture an image with a mobile device of an issue at a location in a facility. An application executing on the mobile device can receive an input associated with the image. The mobile application can transmit image and the input associated with the image to a computing system which can determine a location at which the image was taken in the facility. The computing system can transmit a command to a UAGV to navigate to the determined location of the facility where the UAGV can capture an image using an image capturing device coupled to the UAGV, of the reported issue at the location in the facility. The UAGV can transmit the image to the computing system to confirm the type of the facility issue based on the image captured by the UAGV. The computing system can transmit an appropriate alert after confirming the issue.

Abstract: The invention is a reconditioner for batteries to remove the “memory effect” or “voltage depression”, which is caused by the failure to completely discharge a battery before recharging the battery. The invention places a closed circuit with a low resistance between the positive and negative terminals of a battery. A threshold device is used to stop the current flow after the battery is discharged to a certain level. Some embodiments of the invention provide an indicator to indicate when a battery is sufficiently discharged. Other embodiments also provide a recharger, which recharges the battery after the battery is sufficiently discharged.

Abstract: Precise cutting of pattern strips and pattern pieces from lace and similar patterned fabrics requires correct mutual positioning of the fabric and fabric cutter for precise alignment with the boundary of the pattern pre-existing on the fabric. Patterned fabrics and especially loosely-woven lace are liable to randomly variable stretching and slippage which makes it impossible to cut under the direction of an externally imposed pattern program without regard to the instantaneous location of the pattern pre-existing on the fabric. The invention comprises lace-cutting apparatus and a lace-cutting method including optical scanning of the lace, recognition of the pattern boundary, and mutual alignment of the fabric with the fabric cutter to trace the intended cut line. Different techniques for mutual movement of the fabric and cutter are employed according to whether the pattern boundary is re-entrant or not. Preferred forms of fabric cutter include a hot-wire cutter and a laser beam cutter.
