Abstract: A communication system (10) for an underground production drill (8), comprising a slave unit (12) comprising a CAN bus interface (14) and an electrical power controller (16) and rechargeable battery (18), said controller (16) configured to monitor a status and regulate charging of said battery (18). The controller (16) and battery (18) encapsulated in a thermally-conductive fire retardant material (10). The slave unit (12) includes a first protocol converter (24) and powered via the power controller (16) and configured to convert between wireless network and CAN bus protocols, and a first wireless transceiver (26) arranged in signal communication with the power controller (16) and first protocol converter (24) and configured to transceive the wireless network protocol and transmit the status of the battery (18). System (10) includes a master unit (28) comprising a CAN bus interface (14), a second protocol converter (30) and a second wireless transceiver (32).

Abstract: The present invention relates to a system and a method for facilitating either one of cigarette sales and cigarette tracking the system includes a package which presents a token or tokens, a user device, and a remote backend. The user device uses an input device, a first processor, a memory device and a first transceiver. The user device is typically a smart phone but may be any other device equipped with an input device which is able to access Global System for Mobile Communications (GSM) communications protocol. If the user device is not a smartphone, token may be an USSD alphanumeric code which is inputted using the input device's keyboard. The use of the device as described herein allows for a cheap, easy-to-manufacture product which also protects cigarettes contained within from degradation or damage.

Abstract: A wirelessly controlled LED lighting system comprising: an LED lighting device further comprised of an LED circuit board with one or more light-emitting diode (LED) chips and an antenna attached to said LED circuit board; an LED drive current source; a wireless radio controller attached to said LED Drive current source; associated packaging, heat-sink and optics; embedded software; and a wireless internet gateway system further comprised of a gateway system device, a control device and application software.

Abstract: A non-slip surface is provided comprising a surface having at least one arcuate lug, said arcuate lug comprising a raised center portion and raised and twisted side portions for preventing slippage. Additionally, a process is provided comprising the steps of cutting an arc into a surface, raising and twisting said arc in relation to said surface by bending said surface along a secant perpendicular to a line connecting the midpoint of said arc and the secant, creating at least one arcuate lug in said surface.

Abstract: A drill housing includes an internal cavity for receiving a unitary tubular support member rotatably supported by bearing assemblies in the drill housing. The tubular support member is connected through meshing gears to a drive shaft of a rotary motor mounted externally on the drill housing. An upper end portion of the tubular support member is rotatably supported by a first bearing assembly and is nonrotatably connected to a drill retaining member that extends into a central bore of the tubular support member. The drill retaining member has a socket for receiving the shank of a drill steel. A lower end portion of the tubular support member is rotatably supported by a second bearing assembly. An enlarged intermediate body portion of the support member separates the upper and lower end portions and supports the first and second bearing asemblies.

Abstract: A pump system includes a source of fluid under pressure conveyed into a fluid chamber containing meshing gears which are rotated by the pressurized fluid to, in turn, transmit rotation to a unitary valve member positioned in a housing. Rotation of the gears also displaces fluid at a preselected flow rate through an inlet port of the housing and into a first inlet port of the rotary valve member. During the first one half cycle of rotation of the rotary valve member, fluid is conveyed through a first set of aligned outlet ports of the valve member and the valve housing to a water pump for displacing a water piston. The water piston is displaced to convey water through a first conduit. During the second one half cycle of rotation of the rotary valve member, fluid is conveyed through a second set of aligned outlet ports of the valve member and the valve housing to displace the water piston in an opposite direction to convey water through a second conduit.
