An electrostatographic toner image reproduction machine is provided for producing toner reproductions of original images. The reproduction machine includes a frame; a movable image bearing member mounted to and having a path of movement within the frame; and electrostatographic process devices mounted for forming a toner image, transferring and fusing the toner image onto a copy sheet; and at least one status parameter defining a quality condition of the formed, transferred and fused toner images. The reproduction machine also includes measuring devices for measuring the at least one status parameter; at least first and second different machine speeds at which to operate the machine; and a machine controller connected to the measuring devices for automatically changing the machine speed in response to each of the at least one status parameter so as to ensure continued production of high quality toner images. The machine controller is programmed to read a Start-Of-Copy (SOCS) status of the at least one status parameter; a rate of change (ROC) of the at least one status parameter; an acceptable Normal End-Of-Copy value range (NEOCVR) of the at least one status parameter; and a Default machine speed (DMS) of the machine. The machine controller is also programmed to measure the at least one status parameter and calculate a Predicted End-Of-Copy Value (PEOCV) of the at least one status parameter given the DMS of the machine, to compare the PEOCV with the NEOCVR, and to automatically change the Default machine speed (DMS) of the machine to an Adjusted Machine speed (AMS) in order for the PEOCV of the at least one status parameter, given the AMS, to be within the acceptable NEOCVR, thereby ensuring continued production of high quality toner images.

A system comprising a power supply, an emergency warning light and a speaker, in combination with a control head. One or more processors controls operation of the system in response to received user input and provides system status for display. Storage media encoded with emergency warning light system instructions for execution by one or more of the processors controls the actuation of the emergency warning light system and controls light patterns generated by the emergency warning light system. The storage media is further encoded with siren system instructions for execution by one or more of the processors for controlling the actuation of the siren system and for controlling audible sounds generated by the siren system.

A solar light bar includes a battery isolator adapted to be connected between a bus and a vehicle charging system for isolating a vehicle battery from the bus and for selectively connecting the bus to the charging system. A light source switch connects the light source and the bus for selectively electrically connecting the light source to the bus. When the light source switch is closed, the light source is energized by electricity from at least one of the solar panel, the charging system and the auxiliary battery. When the light source switch is open the light source is isolated from the bus. The auxiliary battery is adapted to be selectively charged by electricity from at least one of the solar panel and the charging system.

A light bar may include a light head with chip-on-board (COB) light emitting diode (LED) and an optic component mounted adjacent to the COB LED. The light bar may comprise short and long center modules. The light bar may include a plurality of housing modules where each housing module includes a light head and a lens cover having a top portion that is substantially impervious to ultraviolet radiation, and a lens portion extending downward from the top portion in generally opposing relationship with the light head. The light bar may include a circuit board including a wire-to-board connector, and a light head including a wire-to-board connector mated with the wire-to-board connector on the circuit board to electrically connect the light head to the circuit board. The light head may include a holographic diffuser.

Digital circuits determine multiplicative inverses using look-up tables which, in response to an address signal, provide a signal indicating a multiplicative inverse. The look-up tables store values indicating inverses for numbers between 1 and 2. The circuit factors a value to be inverted as product a power of two and a factor between 1 and 2. An address signal indicating the factor is applied to the look-up table, and the look-up table provides a signal which indicates the inverse of the factor. The signal provided by the look-up table is then converted to the proper scale for the exponent N. Factoring and conversion may be accomplished with logical shifts so that no multiplier is required. The look-up table may be compressed by not storing bits of inverses, which are constant or only change once within the range of the look-up table and by only storing look-up values for every other number within the range of the look-up table. A code bit in each look-up table value permits generation of correct inverses for values not stored.

A low cost skid control system is disclosed that incorporates a skid detector circuit for detecting a skid condition in combination with a hold capacitor ramp circuit that maintains the brake release signal beyond the termination of the skid signal from the output of the detector circuit when a severe skid condition is encountered. The level of charge on the hold capacitor ramp circuit is adapted to relate to the severity of the wheel speed departure from the approximated vehicle speed. In one embodiment, this is accomplished indirectly by providing a peak acceleration circuit which stores the maximum wheel acceleration value attained during wheel spin-up when brake pressure is relieved. The peak acceleration value is then utilized to vary the charge rate of the hold-on capacitor during the succeeding braking period. In addition, another circuit is provided that is adapted to rapidly dissipate any remaining charge on the hold-on capacitor when the acceleration of the wheels during wheel spin-up begins to decrease. This helps minimize stopping distance by preventing the release of brake pressure beyond that necessary to complete wheel spin-up.

A light bar and/or a siren controlled by a control head via control signals on power lines connected to the control head, the light bar and/or the siren. Isolated power line communication (PLC) modules between the light bar, the siren and the control head transmit the control signals over the power lines.

An anti-lock braking system includes a mechanism for releasing a brake and a digital circuit for determining a wheel velocity and controlling the mechanism to prevent the brake from locking. The digital circuit uses a look-up table which, in response to an address signal, provides a signal indicating a multiplicative inverse of a number between 1 and 2. The circuit receives a measured time for a wheel to move a fixed distance and factors the time as product a power of two and a factor between 1 and 2. An address signal indicating the factor is applied to the look-up table, and the look-up table provides a signal which indicates the inverse of the factor. The signal from the look-up table is then converted to the proper scale for the time. Factoring and conversion may be accomplished with logical shifts so that no multiplier is required. The look-up table may be compressed by not storing bits of inverses, which are constant or only change once within the range of the look-up table and by only storing look-up values for every other number within the range of the look-up table. A code bit in each look-up table value permits generation of correct inverses for values not stored.
