Abstract: Therapeutic treatment as well as prophylactic measures are provided by topical application of compositions containing an aryl 2-acetoxyethanoic acid to eradicate or prevent the development of axillary foul odor, foot malodor and other body odors, e.g. scalp, and skin, nail and follicular infections caused by microorganisms. The compositions are antimicrobial against several organisms that infect the skin and are specifically effective against P. acnes. The compositions are therapeutically effective against folliculitis and perifolliculitis and are useful for other skin lesions, nail and mucosal infections such as impetigo, seborrheic dermatitis, erythrasma and trichomycosis axillaris, associated with or caused by microorganisms. The therapeutic effect of the composition may be synergized or amplified by incorporating a cosmetic or dermatologic agent into the formulation for topical treatment of cosmetic and dermatologic indications.

Abstract: Noise reduction schemes are provided in a radio frequency identification (RFID) system for use with RFID intelligent tags. Fiber optics are used to communicate analog tag response signals from the output of the receiver circuit to the input of a tag response signal analyzing module, which includes a digital signal processor (DSP). The fiber optics creates electrical isolation between these circuit elements breaking ground loops, stopping internal switching noise from the DSP from entering the receiver circuitry, and preventing common mode signals from interfering with the desired RFID tag signal.

Abstract: As shown in FIG. 9, a switching control part 310 detects voltage drops of FET power transistors 81 to 83, and outputs a switching control signal Vd responding with a modulated signal changed in synchronization with a movement of a motor, and a detected operation voltage. The switching operation of a switching transistor 61 is controlled responding with the switching control signal Vd, so that a converted DC voltage of a voltage converting part 52 is controlled. The converted DC voltage of the voltage converting part is supplied to power amplifying parts 11 to 17. The power amplifying parts configured by FET power current-mirror circuits analoguely alter current paths from the converted DC voltage of the voltage converting part to three-phase windings 2, 3, and 4, whereby pulsation of drive currents I1, I2, and I3 to the windings is reduced and a motor vibration is decreased in level.
