Abstract: A workstation for a material handling system is provided. The system may include a plurality of vehicles for retrieving items from a plurality of storage locations located in one or more racks. The workstation is configured to accommodate the vehicles so that the vehicles drive into the workstation and drive upwardly along a track in the workstation. In one configuration, the track is configured to tilt the vehicle at a predetermined angle relative to the horizon as the vehicle is driven upwardly. After the vehicle is tilted to the predetermined angle the vehicle continues to drive upwardly while maintaining the predetermined angle.

Abstract: A waterproof housing to contain and operate an electronic device with capacitive touch screen and electrically conductive outer case includes interfitting pieces configured to form a waterproof shell to removably receive and immobilize the electronic device. One or more electrical circuits extend within the shell between the outer case of the electronic device installed in the shell and one or more respective control regions of the screen. Manual actuators such as buttons are provided in openings through the shell to selectively manually complete each circuit from outside the housing.

Abstract: A waterproof housing to contain and operate an electronic device with capacitive touch screen and electrically conductive outer case includes interfitting pieces configured to removably receive and immobilize the electronic device. One or more buttons through the housing are aligned opposite control regions of the screen and exposed for user depression. Different conductive polymer members connect at least distal tips of the buttons with the outer case to provide electrical connection between the case and a control region of the touch screen with depression of the button overlying the region. Some members further provide sealing and spring functions.

Abstract: A toy vehicle comprises a lift mechanism which allows the toy vehicle to be lifted from a support surface in a lifting motion and roll end over end over end. The lift mechanism includes a lift arm pivotally mounted to a housing of the toy vehicle. A lift arm actuating motor is coupled to a lift arm drive screw that is in threaded engagement with a lift arm drive nut. A strut is coupled between the drive nut and the lift arm. In operation, the lift arm actuating motor drives the lift arm drive screw and causes the lift arm drive nut to drive the strut and move the lift arm into an extended position, causing the lift arm to engage a support surface to lift the toy vehicle. In the extended position, the toy vehicle is sufficiently rounded to permit the vehicle to roll end over end over end.

Abstract: A remote-controlled toy vehicle includes a plurality of road wheels supporting the toy vehicle for movement. A driving motor is selectively reversible between first and second directions of rotation and is drivingly connected to at least one of the road wheels through a drive mechanism. The drive mechanism operates in at least two modes, such that operation of the driving motor in either of its opposing directions of rotation causes rotation of the at least one road wheel to propel the toy vehicle in only a forward vehicle direction. A second motor can provide braking action or a third mode of forward vehicle propulsion.

Abstract: A toy vehicle has a chassis, at least a first drive wheel rotatably attached to the chassis and at least a first link having a first end pivotally coupled with the chassis. At least a first non-powered wheel is operably coupled with the second opposing end of the first link. The first link has two operative positions: a first, fully-retracted operating configuration in which the first link is wrapped at least partially around the chassis crossing the drive wheel axis of rotation and a second, extended operating configuration in which the first link is pivoted away and extended from the chassis. A second link can be pivotally coupled between and with the chassis and first link. Forces acting on the toy vehicle resulting from driving the first drive wheel can cause each link to pivot with respect to the chassis.

Abstract: A toy vehicle comprises a lift mechanism which allows the toy vehicle to be lifted from a supporting surface in a lifting motion. The lift mechanism includes a rotary member which engages a lifting lever hingedly attached to a chassis of the toy vehicle. In operation, the rotary member is abruptly moved by a biasing member into engagement with the lifting lever. The rotary member moves the lifting lever into an extended position, causing the lifting lever to engage the supporting surface, to lift the toy. The toy vehicle includes features to help permit operation of the lift mechanism only when the toy vehicle is in a proper operational condition.

Abstract: An apparatus for displaying filename information on a floppy disk is disclosed. The apparatus utilizes a modified floppy disk housing and a modified floppy disk drive to automatically label the floppy disk with the filenames being copied to or deleted from the disk. The modified floppy disk housing includes an apparatus for visually displaying information indicative of the data stored on the floppy disk when the floppy disk is not inserted in a floppy disk drive.
