Abstract: A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

Abstract: Drivetrain assemblies for personal care devices to generate controllable power tapping motion alone or with controllable sweeping motion. The drivetrain assemblies include a drivetrain shaft at least partially contained within a body portion. The drivetrain shaft is further configured to engage a brush head member. Some drivetrain assemblies include a single actuator for generating periodic linear movement, wherein the drivetrain shaft transmits the linear movement to the brush head member via a pivoting motion and/or a translational motion. Other drivetrain assemblies include the actuator for generating periodic linear movement and a motor on the drivetrain shaft to periodically rotate the shaft about a central axis.

Abstract: A personal care device including a body portion; a cleaning unit having a set of cleaning elements, the set of cleaning elements extending in an axis of alignment; a controller and an actuator assembly arranged to be driven by the controller. The actuator assembly includes an actuator configured to generate first and second periodic movements, wherein the first and second periodic movements operate at different frequencies or out-of-phase with each other. The first periodic movement causes the cleaning elements to move in a first direction about a central axis of the personal care device or along a line that is tangential to a platen of the cleaning unit. The second periodic movement causes the cleaning elements to move in a second direction that is different than the first direction, wherein the second direction is normal to the platen of the cleaning unit.

Abstract: Systems and methods to validate RFID counts may be provided. A business may affix temporary or permanent location tags with barcodes throughout an area to be counted, and the location tags may then be recorded. Manual counters may perform a piece count of items associated with each location tag. RFID counters may perform an RFID read of items associated with each location tag. All RFID reads may be associated with their most likely location tag. The manual piece count may be compared to the total of RFID tags assigned to each location tag. Locations may be rejected where the totals do not match. Locations rejected by the manual piece count comparison may then be barcode scanned and compared to the RFID reads for each location tag required to be barcode scanned. Resolution may be performed for locations where the barcode item counts do not match the RFID item counts.
