Abstract: Systems, methods, and apparatus are described herein for pre-winding a motorized roller shade. The motorized roller shade may include a roller tube, a flexible material attached to the roller tube, a motor drive unit, and mounting brackets configured to support respective ends of the roller tube. The roller tube of the roller shade may be slid to an extended position. A configuration procedure may be determined to have been initiated. The flexible material may be secured, for example, to prevent the flexible material from unrolling. The roller tube may be wound a predetermined number of rotations with the flexible material and a hembar of the roller shade secured, for example, to prevent the flexible material from being raised or lowered. Winding the roller tube may include pre-winding a spring that is coupled to the roller tube. The flexible material may be unsecured when the roller tube has been pre-wound.

Abstract: A motor drive unit may include a motor and a magnetic brake. The motor may be configured to be located within a motor drive unit housing of the motor drive unit. The motor may include a motor drive shaft defining a motor drive shaft rotational axis in a longitudinal direction. The motor drive shaft may be configured to rotate a roller tube of a motorized window treatment. The magnetic brake may include a stationary portion that includes a first plurality of magnets and a rotating portion that includes a second plurality of magnets. The first plurality of magnets may be configured to repel the second plurality of magnets such that repulsion between the first plurality of magnets and the second plurality of magnets generates a holding torque to prevent the motor drive shaft rom rotating when the motor is not driving the motor drive shaft.

Abstract: A motorized window treatment may include a roller tube, a flexible material attached to the roller tube, and a motor drive unit. The motor drive unit may be disposed within a cavity of the roller tube. The motor drive unit may include a motor, a gear assembly, and a shaft stabilization member. The motor may include a drive shaft extending from a drive end of the motor and a rear shaft extending from a non-drive end of the motor. The drive shaft and the rear shaft may be configured to rotate about a longitudinal axis. The gear assembly may be operatively coupled to the roller tube and the drive shaft. The shaft stabilization member may be operatively coupled to the rear shaft. The shaft stabilization member may be configured to dampen axial and/or radial forces in the motor drive unit.

Abstract: An arrangement and system places an external cable into a slot. The arrangement includes a slot extending from a first end to a second end. The slot includes a recess configured to receive a cable therein. The arrangement includes a movable component configured to slide along a length of the slot. The movable component includes a first end and a second end. Sliding the movable component along the slot in a first direction from the first end to the second end of the slot one of frees a first portion of the cable from the slot or places a second portion of the cable in the slot.

Abstract: A dongle includes: a battery configured to provide direct current (DC) power to a device to which the dongle is electrically and mechanically connected. The battery is adapted to be removed and replaced by another battery. A heat sink configured to dissipate heat generated by the battery is adapted to be removed and replaced by another heat sink.

Abstract: A motorized window treatment may be configured to adjust a position of a covering material to control the amount of daylight entering a space. The motorized window treatment may include a DC power source for charging an energy storage element, such as a supercapacitor and/or rechargeable battery. The energy storage element may be configured to provide power for the operation of a motor used to adjust the position of the covering material. The energy storage element may discharge when providing power to the motor and may charge such that the current it draws from a battery is at a desired average current level that extends the lifetime of the battery.

Abstract: A local magnetic resonance (MR) radio frequency (RF) coil (12, 70, 90) includes a fixed size coil housing (19, 72) with an internal opening (26) which receives a portion of a subject anatomy for imaging. The internal opening (26) includes a narrowed portion (28) and a divergent portion (30) which accommodates variable sizes of subject anatomy. A first size of antenna (84) is disposed in the housing (19, 72) adjacent the narrowed portion (28) of the opening and at least a second size of antenna (86) larger than the at least first sized antenna (84) adjacent the divergent portion of the opening.

Abstract: A dongle, and an apparatus to charge and replace components of the dongle are described. The dongle includes: a battery configured to provide direct current (DC) power to a device to which the dongle is electrically and mechanically connected, the battery being adapted to be removed, and replaced by another battery; and a heat sink configured to dissipate heat generated by the battery, the heat sink being adapted to be removed, and replaced by another heat sink.

Abstract: An apparatus includes a magnetic resonance (MR) receiver. The MR receiver includes at least one galvanic connector, at least one digitizer connected to the at least one galvanic connector, a power supply connected to the at least one digitizer, and a housing. The at least one galvanic connector connects in a connected configuration to a radio frequency (RF) coil element of at least one local RF coil to receive MR signals. The at least one digitizer converts the received MR signals to a digital format. The power supply provides power to operate the at least one digitizer. The housing is configured to removably attach to a housing of at least one local RF coil in the connected configuration to enclose the at least one galvanic connector and at least one digitizer with the housing and the attached the at least one local RF coil housing.
