Abstract: Asynchronous fallback save operations herein (also referred to herein as a background save) provide a means for saving very large transactions from a client device within a stateless architecture. When dealing with large transactions, it may take a long time to process records—so long that the connection between the server and the client may time out, causing the user to lose all work or progress that was being saved. Thus, the present technology serves to prevent this “time out” problem while simultaneously allowing users to continue working on something else while a save is still completing. In some implementations, once a user has submitted a save request, the save operation may be carried out in a background thread pool, allowing the user to continue move on to a new task.

Abstract: An imaging system comprises a laser source for emitting a beam, a photoconductive surface, a scanning device and a controller. The controller designates at least a first part and a second part of each line of image data, corresponding to a first part and a second part of each associated sweep of the beam. The laser source is modulated based upon the first part of the line of image data during the first part of a first one of the associated sweeps of the beam. The laser source is not modulated according to image data for the second part of the first one of the sweeps. During the first part of a second one of the associated sweeps of the beam, the laser source is not modulated based upon image data. However, the laser source is modulated based upon the second part of the line of image data during the second part of the second one of the sweeps.

Abstract: An electrophotographic imaging device comprises generally, an image transfer station configured to transfer a toned image to a substrate, a fuser assembly configured to fuse the toned image to the substrate and a transport device configured to transfer the substrate from the image transfer station to the fuser assembly. The device further includes a controller for controlling a first process rate of the image transfer device and a second process rate of the transport device. The controller has a mode of operation wherein the first process rate is different from the second process rate when a hand off is performed to pass the substrate from the image transfer station to the transport device.

Abstract: A turbidity sensing mechanism for a dishwasher is connected in the fluid circulation conduit between the pump and the spray mechanism. The mechanism includes a hollow housing enclosing a hollow transparent tube connected in fluid flow relationship with the conduit. A source of electromagnetic radiation and a radiation-to-frequency sensor are positioned inside the housing on opposite sides of the tube.

Abstract: A system and method for adjusting the operating cycle of a cleaning appliance. In the present invention, a controller having a decision system receives turbidity and temperature measurements from a turbidity sensor and a temperature sensor and uses these measurements to adjust the operating cycle of the machine to the level of soil of the articles to be washed, the rate of soil removal, and the temperature of the water used for washing. In its preferred form the decision system is a fuzzy system that includes a fuzzy rule base fired as input values from the liquid temperature and liquid turbidity sensors are received. The decision system matches the rules in the fuzzy rule base to the input values and outputs a confidence value, which is used by the decision system to adjust the operating cycle.

Abstract: A turbidity sensor holder system having a container with a projection for collecting fluid samples in a machine for cleansing articles is provided. Collector channels are situated in the container projection to collect the fluid to be sampled. One or more vent channels are also provided in the container projection for conveniently venting a reservoir in the container. The present invention with the foregoing collection capability allows the turbidity of the cleansing fluid to be accurately measured without affecting the performance capacity of the sensor.

Abstract: A machine, such as a dishwasher or clothes washer, incorporates a device for measuring machine load that includes a sensor for detecting power consumption surges. The machine may further include a frame for containing articles, a power utilization system for circulating or distributing a liquid in the frame, and a controller, responsive to the device, for controlling the amount of liquid provided to the frame.

Abstract: Load retention devices for material handling vehicles are inadequate in maintaining load position and inflexible in load transfer operations. First and second blocking devices having elevationally movable gates are mounted adjacent opposite sides of the frame of a material handling vehicle and adjacent a load supporting apparatus. The first and second gates are guided for elevational movement between a first position above the load supporting apparatus at which a load on the load supporting apparatus is blocked from side passing movement and a second position beneath the load supporting apparatus at which the load is free to pass the first and second sides. A first power device is provided for selectively moving the first gate member between the first and second elevational positions and a second power device is provided for selectively moving the second gate between the first and second positions.

Abstract: An improved touch control circuit arrangement for electrical appliances having one or more electrical loads to be individually controlled in accordance with user selected power settings. Each load has associated with it a power relay for coupling the load to an external power supply. Each relay is coupled to a latch circuit operative when set to close the relay and when reset to open the relay. The touch control arrangement includes a matrix array of touch keys having an input line for each row and an output line for each column to facilitate the multiplexing of touch key information to the microprocessor in conventional fashion. However, the OFF keys are continuously enabled and coupled to the reset input of the associated latch circuit such that user actuation of an OFF key directly resets the relay control circuit for the associated load. This enables the user to turn off the load independent of the microprocessor.

Abstract: Apparatus and method for detecting a failure in an automatic defrost system for a refrigerator. A current sensor means monitors the current supplied to the defrost heater and generates an "on" signal when current is sensed in the defrost heater circuit. A microprocessor determines the "off" time, that is the time between successive "on" signals, and compares this time to a predetermined reference time longer than the normal "off" time. A user discernible signal is generated upon detection of an "off" time greater than the reference time, signifying to the user that the defrost system is not operating properly, and corrective action may be necessary.

Abstract: An improved over-temperature warning system for a refrigerator/freezer appliance comprises a temperature sensor responsive to the temperature in the freezer compartment of the appliance and logic circuitry responsive to the sensor operative to detect a first over-temperature condition when the sensed temperature is greater than a first reference temperature and less than a second reference temperature and to detect a second over-temperature condition when the sensed temperature is greater than the second reference temperature. The logic circuitry times the duration of the first and second over-temperature conditions and provides a user discernible warning signal when the first condition exceeds a first predetermined time period or when the second over-temperature condition exceeds a second predetermined time period shorter than the first time period.

Abstract: Apparatus and a method for detecting fault conditions in an automatic icemaker system of the type having an ice forming mold and an electric motor and mold heater which are energized during ice cube ejection cycles. A current sensor monitors current in the icemaker motor and mold heater circuit and generates an "on" signal when current is detected. A microprocessor measures the duration of the "on" signals and the elapsed time between successive of "on" signals. A diagnostic code is displayed signifying a fault condition in the icemaker circuit when the time between successive "on" signals is less than the normal time required to freeze cubes or the duration of an "on" cycle exceeds the normal ejection time.

Abstract: A power control arrangement for an automatic surface unit in a cooking appliance which enables the user to select Warm, Simmer, Boil and Fry cooking modes and to select from a plurality of heat settings for each mode. The heat settings for each mode have associated with them a minimum steady state temperature and a steady state power level. The control system compares the output from a utensil temperature sensor with various reference values determined by the mode and heat setting selected and depending upon the comparison, operates the surface unit at the corresponding steady state power level or at a transient power level to rapidly bring the utensil temperature to the desired temperature for the selected mode and heat setting with minimum temperature overshoot.
