The invention is an equipment or vehicle battery circuit cutoff device that mounts at the battery chassis ground mounting hole and accepts the original (in place) battery ground cable (single cable) to provide a secure electrical connection in the use configuration (HOT) and a simple quick, safe, and absolute change of state to the electrical cutoff configuration (CUT). The device employs a heavy compression spring that clamps the battery ground cable into the device when compression spring tension is released against the cable end and allows the quick release of the ground cable when a threaded stud knob or a lever assembly lifts the spring tension to allow the ground cable to be quickly removed. There is no internal switch in the device; the only switch being the presence (HOT) or absence (CUT) of the ground cable in the cutoff device insertion slot. Maximum current flow is supported with this design since the cable is locked against a heavy copper bar in the closed circuit state (HOT) so that the current flow is limited only by the capacity of the cable rather than the configuration of internal cutoff switch contacts. The cable clamping force in the closed circuit (HOT) position is constant and resistant to equipment vibration since the clamping force is derived from a high force (40 foot pounds or greater) compression spring rather than a bolt which may vibrate loose and/or may not have been adequately tightened by the equipment operator.

A gaming system for conducting a multi-player wagering game includes a multi-touch table surface that is touched by a handheld electronic wager input device (EWID) carried by a player for placing wagers on a wagering game displayed on the multi-touch table surface. Each EWID carried by a player has an associated unique identification code, which is linked to the respective player's account. Players indicate an amount to be wagered by touching the EWID to designated wager amount areas, then place the wager by touching the EWID to a designated wagering area. Because each EWID is uniquely associable with distinct player accounts, the gaming system can support any number of players placing wagers. The funds remain safe in the player account and no funds are stored on the EWID. Only the identification code is detected, which is compared with the associated player account before allowing that player to place wagers.

A system for facilitating package delivery or pickup at premises of senders or recipients has a package door that is used for receipt and collection of packages. The package door includes an input device for entering package information and an image capture device for visually recording the arrival of a courier. Based on the package information entered via the input device, the system determines whether the package information matches a predetermined value, such as a package tracking number. The system may automatically unlock the package door if the package information matches such predetermined value. In other embodiments, a user may remotely monitor the package information and/or information from the image capture device to determine whether to provide inputs for unlocking the package door. The system logs the package information received from the input device and the image capture device.

The present invention relates to a method of evaluating at least one operating parameter of a motor vehicle. A system variable relating to an operating parameter of the vehicle is measured. A look-up map (A; S; B) associated with the operating parameter is accessed. The look-up map (A; S; B) comprises of one or more sets of threshold values (R0, R1, R2, R3, R4) and a comparison is made between the measured system variable and the threshold values (R0, R1, R2, R3, R4). An economy rating (E1, E2, E3, E4, E5) is obtained from the look-up map and an indicator output based on the economy rating (E1, E2, E3, E4, E5) to provide the driver with feedback. The present invention also relates to a device for providing driver feedback.
