Abstract: Apparatus and associated methods relate to a pest repelling magnetic field generating device (PRD) having a temperature sensor to detect the temperature of a solenoid coil during operation. The detected temperature to be used to ensure that the PRD operates within an ideal temperature range. Additionally, a fan is oriented within a housing of the PRD to force the flow of air from inside a housing of the PRD to outside a housing the PRD. In an illustrative example, the PRD may shut off if the temperature of the solenoid coil moves outside the ideal temperature range. By operating the PRD within an ideal temperature range, the service life of the PRD may be extended. Further, the fan may mitigate dust collection within the housing of the pest repelling magnetic field generating device.

Abstract: Directing an input light beam into a laser diode operated at a power below that required for lasing stimulates emissions, resulting in an amplified output beam. A dynamic steering system can focus the input beam onto front face of the laser diode. The steering system optionally includes an optical element mounted solely on piezoelectric actuators. Control signals for the actuators in the steering system control a base position and cause alternating movements of the optical element. A detector measuring optical power leaking from a back face of the laser diode can determine the power of the amplified beam that exits from the front face, and derivatives of the measured power with respect to the alternating movements indicate required adjustments of the base position. A polarizing beam splitter and quarter-wave plate in the path of beams can separate the input and amplified beams.

Abstract: A hairdressing comb (10) comprises a series of spaced pairs of hair-lifting teeth (16.1, 16.2), the teeth of each pair defining between them a gap 18 into which hair can enter. Each hair-lifting tooth has a hair-lifting formation (20.1, 20.2), the hair-lifting formations of each pair of teeth both extending into the corresponding gap (18). The hair-lifting formations (20.1, 20.2) of each pair of teeth (16.1, 16.2) are staggered with respect to one another in the longitudinal direction of the teeth (16.1, 16.2), and the one hair-lifting formation (20.2) extends into the gap (18) to a point laterally beyond that to which the other hair lifting formation (20.2) extends into the gap (18).
