  • Patent number: 11946025
    Abstract: This invention relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. The whitening agents are further characterized by having a dispersion component value of the Hansen Solubility Parameter of less than or equal to about 17 MPa0.5. This invention also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.

  • Patent number: 11042285
    Abstract: A system for controlling the operation of a human machine interface (HMI) device located in a vehicle configured to carry a passenger and a driver. The system includes an electrode positioned in a vehicle seat and a signal generating device configured to provide a signal to the electrode. The electrode transmit the signal through the occupant of the seat and the HMI device detects the signal when the occupant contacts the HMI device. The system is configured so that the HMI device operates in a first mode in response to exposure to the signal and in a second mode if the signal is not detected.

  • Publication number: 20030085631
    Abstract: A sensor system (30) detects the occurrence of angular rotation of a pivotable member (22), such as a door, relative to a fixed member (16), such as the base of a mailbox (10). The sensor system includes a sensor strip (34) positioned so as to change orientation when the door is opened or closed and generate an electrical signal. An RF transmitter (62) signals a receiver (60) at a remote location when the sensor strip registers the opening or closing. A filter (72) filters out noise to inhibit accidental signaling of door opening and/or closing when opening or closing has not occurred. A charge tuner (80) stores charge generated by the piezo-electric element to maintain the transmitter signal beyond the period of opening or closing.

  • Patent number: 6473304
    Abstract: A power supply and a method of manufacture therefor. The power supply includes a circuit board containing conductors for interconnecting electrical components of the power supply and a thermally-conductive case having an integral electrically insulating layer. The thermally-conductive case forms a reservoir to receive the circuit board therein. The power supply further includes a power semiconductor device having a body connected in thermal communication with the thermally-conductive case and terminals coupled to the conductors of the circuit board. The power supply still further includes an encapsulant, located within the reservoir, capable of ensconcing the power semiconductor device and the electrical components. Additionally, electrical leads extend from the power supply that allows the power supply to be coupled to a printed wiring board.
