Abstract: A method of operating an elevator system is provided and includes recognizing that brakes of an elevator car fail to drop upon brake power being removed, temporarily hovering the elevator car in place to allow the elevator car to be emptied, controllably moving the elevator car in a direction of imbalance, which is defined in terms of relative weights of the elevator car and a counter-weight and torque applied to the elevator car for driving the elevator car upwardly or downwardly, to either a top or a bottom of a hoistway and confirming that the brakes are failing to drop or provide sufficient holding torque.

Abstract: An elevator drive configured to control power to an elevator motor includes a plurality of first (upper) inverter switches and a plurality of second (lower) inverter switches. A processor is configured to provide control signals to control operation of the inverter switches. A first signal buffer between the processor and the inverter switches is configured to selectively prevent any control signals from turning on any of the inverter switches when the motor should not receive power. A second signal buffer between the processor and the inverter switches is configured to selectively bypass the first signal buffer, prevent any control signals from turning on the first inverter switches, and allow a control signal from the processor to turn on the second inverter switches to provide motor braking.

Abstract: An expression cassette for gene silencing and replacement, including, in operable communication, a promoter, an expression attenuator, a nucleotide sequence encoding a gene for a replacement target protein, and an shRNA sequence for knockdown of an endogenous variant of the target protein, wherein the promoter, the expression attenuator, the nucleotide sequence encoding the gene for the replacement target protein, and the shRNA are expressed as a single transcript. Also included are expression vectors and cells. Also included are methods of silencing and replacement of a target gene in a cell in culture by transforming the cells with the expression vectors described herein. Also included are minimal expression cassettes suitable for therapeutic methods.

Abstract: An elevator energy management system includes a first variable frequency drive configured to deliver electrical power from a power source to an elevator machine during a first operating condition and to receive regenerative energy from the elevator machine during a second operating condition. A second variable frequency drive is configured to selectively receive regenerative energy from the first variable frequency drive during the second operating condition. At least one energy receiving device is coupled with the second variable frequency drive. The energy receiving device is configured to receive regenerative energy from the second variable frequency drive.

Abstract: This disclosure relates to a system and method configured to identify and, if necessary, respond to conditions indicative of electromagnetic brake temperature, and in particular relates to passenger conveyers, such as elevators, employing the system and method. More specifically, an example passenger conveyer system includes an electromagnetic brake and a controller configured to identify a condition indicative of a temperature of the electromagnetic brake approaching a boundary of a predetermined operating range.

Abstract: An illustrative example embodiment of an elevator brake control device includes at least one primary switch configured to selectively conduct current for lifting all of a plurality of brake applicators. A plurality of secondary switches are each associated with one of the brake applicators. Each of the secondary switches is configured to selectively conduct current for lifting the associated one of the brake applicators. The plurality of secondary switches are between the primary switch and the associated one of the brake applicators.

Abstract: An infant swaddle, and method of using thereof. In accordance with an embodiment the swaddle comprises a body portion, wing portions, and either one or more, or a pair of, arm pockets positioned to the side of the infant's torso so that, when the infant is placed into the body portion and their arms placed into the arm pocket or pockets, the infant's arms are gently initially positioned outwards, with their hands upwards, generally along the orientation of the wings. The wings can then be folded over and fastened which gently folds and constrains the infant's arms in the pockets, so that their hands are positioned at the midline of their chest.

Abstract: A method for structuring an equity issue comprising: (a) establishing a holding company as an owner of a closed block business entity, wherein the holding company is a subsidiary of a parent company and further wherein an on-going business is a subsidiary of the parent company; (b) representing an on-going business by a first class of common stock issued from the parent company; (c) issuing a second class of common stock in the parent company, wherein the second class of common stock represents an ownership interest in the closed block business entity and wherein the closed block business entity is a lower growth and lower margin business than the on-going business; and (d) classifying proceeds received from the issuance of the second class of common stock as assets of the on-going business.

Abstract: A system for evaluating time requirements for performing maintenance on a maintenance object. One or more processors and memory are operable to provide a form on which a user describes a maintenance task. The described task is made available for maintenance time analysis as at least one of the following: a main task, a subtask of another main task, and an elementary operation. The user is allowed to combine a plurality of described tasks into one or more hierarchies designated by the user. This system provides flexibility to evaluate maintenance task times regardless of whether a level of detail and/or design maturity is minimal or complete.

Abstract: A distance measuring system in which a first station (FIG. 1) radiates a modulated carrier wave and a second station (FIG. 2) receives that wave, and retransmits the modulation on a carrier wave back to the first station, which compares the phases of the original and received modulations. The second station includes a digital counter (19) which accumulates clock pulses denoting the period of the modulation and a second counter is incremented and decremented to reproduce the modulation for retransmission thereof.
