Abstract: An electric power apparatus includes a main planar body having a circular opening that supports a brushless direct-current (BLDC) motor. The motor includes a stator, a rotor, a motor spindle extending through the circular opening, a first end cap formed on a first side of the stator and mounted on the main planar body; and a second end cap formed on a second side of the stator and secured to the first end cap to form a substantially watertight seal around the stator and the rotor. A ratio of a maximum power output of the motor when powered by at least one battery pack to a height of the motor as measured from an upper surface of the main planar body to a top surface of the motor is greater than or equal to approximately 34 watts/mm.

Abstract: An electric motor is provided including a stator, a rotor, a motor spindle coupled to the rotor and extending along a center axis, a first end cap formed on a first side of the stator, a second end cap formed on a second side of the stator and secured to the first end cap to form a first compartment around the stator and the rotor, an electro-magnetic brake module disposed on a side of the second end cap opposite the stator and engaged with the motor spindle, and a motor cover mounted on the second end cap to form a second compartment around the electro-magnetic brake module. The first end cap, the second end cap, and the motor cover form a substantially watertight seal around the stator, the rotor, and the position sensor assembly.

Abstract: A system for searching for keywords and/or keyphrases and/or keysymbols in a data memory containing bit-mapped image patterns for words and/or symbols constructs a keyword/phrase/symbol recognition pattern of the keyword/phrase/symbol to be searched for; scans the data memory to access the bit-mapped image patterns; and processes the constructed keyword/phrase/symbol recognition pattern and the accessed bit-mapped image patterns by correlation to determine the presence in the data memory of a bit-mapped image pattern for the keyword/phrase/symbol.

Abstract: The present specification describes and claims a shower screen unit. The unit basically comprises a roller blind of, for example, woven glass fiber material, housed in an elongate extruded plastics material casing. Two freely rotatable water absorbent sponge rollers are also housed in the casing and the screen passes therebetween, the rollers engaging opposite sides of the screen. The unit can be secured in position by an adhesive sponge layer on the casing and can be decorated by a detachable valance. The lower edge of the screen is divided for use in gripping a wall defining part of a shower area.
