Abstract:
A lock programming device (10) is for use with a lock system (40) including a computer (2) and a one door lock(s) having a control. The computer has RAM (6), a storage device (7), and a program for generating lock code data files in response to user input. The lock control has memory (4a) for storing a lock code data file(s) and is configured to operate the lock when receiving input corresponding to the code file. The programming device (10) includes a base (12) disposeable in a user's hand and a flash memory (14) connected with the base for storing at least one data file. A controller (16) connected with the base is coupled with the flash memory and coupleable with the computer. The controller communicates with the computer to write a data file in RAM directly to the flash memory and communicates with the lock control to transfer the data file from the flash memory to the lock memory.
Abstract:
A lock system (10) includes a lock adjustable between locked and unlocked configurations and at least one and preferably two input devices (30, 22) each configured to generate or/and receive user input, each input having a value. A controller (16) is operatively with the lock, coupled with the input device(s) (22, 30) to receive user input, and has memory with at least first and second data files, the first file having at least one stored value. The controller (16) is configured to receive first and second user inputs, to compare the first input value with the first file(s) value, and to store a particular second input value within the second data file when the particular first input value correspond with at least one valuein the first file, thus enrolling the user. Thereafter, the lock is preferably unlocked using only the second user input, which is carried by a key unit or a user physical feature.
Abstract:
A fluid channeling device (10) is for a down-hole drill assembly (1) having a central axis (1c) and advanceable into a hole in a downward direction (D) along the axis (1c). The assembly (1) includes a drill member (2) with an inner surface (2a) bounding a central bore (2b) and an outer surface (2c). The channeling system includes at least one passage (12) provided within the drill member (2) so as to extend generally between the drill member inner (2a) and outer surfaces (2c). A generally annular channeling member (14) is disposeable about a portion of the drill member (2) and has at least one inlet port (20), at least one discharge port (16), and a passage (12) extending between the inlet (20) and discharge ports (16). The inlet port (20) is fluidly connectable with the drill member passage (12) to fluidly couple the central bore (2b) with the discharge port (16). The discharge port (16) is configured to direct fluid generally externally of the drill assembly (1) and generally in an upward direction (U) along the axis (1c).
Abstract:
An access control system is for at least first and second doors each having a lock adjustable between locked and unlocked states. A key has a code including first and second segments. A first controller coupled with the first door lock has a stored value and is configured to receive the key code and to compare at least the code first segment with the stored value, and unlocks the first lock when the code first segment corresponds with the stored value. A second controller coupled with the second door lock has a stored value and is configured to receive the key code and to compare at least the second code segment with the second stored value, and unlocks the second lock when either the code second segment corresponds with the second stored value or both code segments correspond with separate portions of the second value.
Abstract:
A device is provided for discharging two gases from a vehicle to ambient air, one gas having pressure pulsation of a first magnitude. The device includes an elongated body connected with the vehicle and having a first inlet connected with a first gas source, a second inlet connected with a second gas source, an outlet fluidly communicable with ambient air, and an interior mixing chamber, the two inlets being fluidly communicable with the chamber such that the two gases flow into the chamber. The body combines the two gases within the mixing chamber to form a combined gas having pressure pulsation of a lesser, second magnitude and to discharge the combined gas to ambient air. Preferably, the body includes an outer tubular member having the first inlet and the outlet and an inner tubular member disposed within the outer member and including the second inlet and a plurality of ports.
Abstract:
A conveyor (10) for transporting material (M) includes a drive wheel (12) having a circumferential outer surface (18) and a plurality of openings (20) spaced circumferentially about the outer surface (18). A belt (14) includes an endless body (22) disposed about the drive wheel (12) and having two opposing side edges, a generally circumferential outer surface (26) configured to transport material (M) and a generally circumferential inner surface (28). A plurality of projections (30) extend from the belt inner surface (28), each projection (30) being separately disposeable within each one of the wheel openings (20) such that rotation of the wheel (12) drives the belt (14) to circulate along a centerline. The belt also includes at least one and preferably two substantially continuous circumferential surface sections located generally between the projections (30) and the belt edges. One or more support rails (16) each have a plurality of rollers (34), the rollers (34) being contactable with one of the belt continuous surface sections such that the rails (16) support the belt (14).
Abstract:
A system is for sensing a property of a material mat from a construction vehicle. The system includes a sensor for sensing the material property and a positioning mechanism connected with the vehicle and with the sensor. The mechanism displaces the sensor between first and second positions with respect to the vehicle as the vehicle displaces with respect to the material mat. The first sensor position is spaced a substantial distance above the mat upper surface. The second sensor position is located proximal to or on the mat surface such that the sensor is able to sense the material property in the second position. A controller operates the mechanism to sequentially displace the sensor from the first to second positions, permit the sensor to remain disposed at the second position for a period of time, and displace the sensor from the second to first positions after the period of time.

Abstract:
A fluid distributor device is for a percussive drill assembly including a generally tubular casing (2) having a longitudinal centerline and a piston (6) disposed within the casing so as to define a reservoir chamber (27) in the casing. The distributor device comprises a generally cylindrical body (12) disposed within the casing and including a central axis, two opposing ends spaced apart along the axis, first and second interior chambers and a port fluidly connecting the two chambers. The body further has a plurality of fluid passages extending between the two ends and fluidly connecting the first chamber with the reservoir chamber and a deflectable retainer portion (16) releasably engaged with the casing so as to retain the body at a desired position with respect to the casing centerline. A valve (7) is disposed within the body and is configured to permit fluid flow through the port and to alternatively prevent fluid flow through the port.
