Abstract: A dental prophylaxis and water conservation device for in-home use. The device includes a tank coupled to the household water supply line and adapted to receive water which causes air contained within the tank to be pressurized. The water and air from within the tank are connected by lines to a handpiece which discharges both mediums simultaneously. Water leaving the tank passes through a container having an abrasive material which is picked up by the water and also discharged. The tank is further coupled to a plumbing fixture, such as a shower head. This enables the tank to be used as a water conservation device by allowing cold water to be purged from a hot water line Into the tank, and subsequently used to provide water to the plumbing fixture. To recycle the purged water, the present invention entrains the water from within the tank as water from the supply line is being provided to the plumbing fixture.

Abstract: An encryption process for a rolling code of a remote keyless entry system.   The encryption process makes use of a command code shift register, a security code shift register, and a sequence code shift register in which the contents of these registers is transmitted from a portable transmitter to a receiver associated with the vehicle in order to perform a desirable function. The command code shift register provides the code of the function to be performed and the sequence code shift register provides a sequence code for updating the sequence of the receiver.   The security code shift register includes a security code which is updated by a first and second pseudo random number generator after each transmission.  Each of two pseudo random number generators include associated shift registers and exclusive NOR gates such that a first bit location and a tap bit location of each of the shift registers are exclusively NORed to provide a first bit location in the shift register.  A series of the bit locations of the first and second shift registers are exclusively ORed together to set the bits of the security code register.

Title: Analytical halftone dot construction for a hyperacuity printer
Inventor: CURRY DOUGLAS N
IPC: B41J2/44
Filed: 1996-02-13
Granted: 2002-12-24
Abstract: A printing device (10) is commanded to print a reference set of intensity values from almost white or highlight regions through almost dark or shadow regions. A measuring device (12) measures the actual outputted printer intensity levels from the printing device (10). An interpolator (14) interpolates the printer intensity levels into a best fit smooth curve plotted against the reference set of intensity levels which produces a non-linear function. A mapping means and converter (24a, 24b) calculate a set of fractional intensity values and densities which produce a linear function when mapped with the printer intensity levels. A dot area parameter calculator (28) calculates a set of dot parameters defining a configuration of a halftone dot required to fill an area within the halftone cell corresponding to each intensity level. For each position of each halftone cell, a measurement processor (30) determines a distance between a current scan position (a,b) and a nearest edge defined by the dot parameters. A gray value calculator (50) calculates a gray value for the current scan position based on the distance and angle to the nearest edge of the dot. The halftone dot is completed when a gray value is calculated for each position within the halftone cell. The gray values are stored in a look-up table (26). When a new image is to be printed, the intensity values are input (54) and the scan position is indexed (52) through all available scan positions to generate corresponding addresses in the look-up table (26), causing the corresponding gray values to be output serially in order for use by a laser diode controller (56) of a laser printer or analogous controllers in other types of printers.

Granted: 2007-01-09
Abstract: A method of making an elongated electrical heating element having a resistance wire with a helical portion extending between two lead pins surrounded by compacted insulating powder in an outer casing. The lead pins are attached to a tightly coiled resistance wire by screwing threaded portions at the inner ends of the lead pins into coiled portions at the outer ends of the resistance wire. The lead pins are pulled further apart to stretch the coiled resistance wire to form the helical portion of the resistance wire and then attached to a resistance meter. One of the lead pins is then rotated relative to the other lead pin to adjust the effective electrical resistance of the heating element to an accurate and uniform valve. The resistance wire and lead pins are mounted in an outer casing which further stretches the helical portion to a predetermined length. The outer casing is then filled with insulating powder in a conventional vibrating filling machine. Finally, the casing is compressed to compact the insulating powder around the heating element.

Abstract: The present invention relates to a process for providing connections of the materials making up disposable absorbent articles. In particular baby diapers, incontinence products and sanitary napkins which are fabricated in continuous processes are beneficially held together by soldering the materials where connections of them are desired. Replacing the currenlty used technique of adhesively attaching materials by soldering materials has the benefit of having non sticky surfaces once the solder is cooled to a temperature below its solidifying temperature. This is highly desirable where the otherwise sticky surface comes into contact with the skin of users of disposable absorbent articles or could cause adhesive build up on machine parts during the manufacturing of such articles.
