Abstract: An elevator car door control system includes a clutch and an interlock assembly. The clutch may include a stationary base and a slidable base movably attached to the stationary base. The stationary base may be adapted for attachment to a car door of an elevator car. The interlock assembly may include a locking arm operatively connected to the slidable base of the clutch and moveable from a locked position preventing translation relative to the elevator car to an unlocked position. When the car door is in a closed position, a door opening sequence may commence causing the slidable base to move relative to the car door, but the car door will only open if the slidable base presses against an object, such as a roller on a hoistway door, in which case the locking arm of the interlock assembly moves from the locked to the unlocked position.

Abstract: Anomalous control and data flow paths in a program are determined by machine learning the program's normal control flow paths and data flow paths. A subset of those paths also may be determined to involve sensitive data and/or computation. Learning involves collecting events as the program executes, and associating those event with metadata related to the flows. This information is used to train the system about normal paths versus anomalous paths, and sensitive paths versus non-sensitive paths. Training leads to development of a baseline “provenance” graph, which is evaluated to determine “sensitive” control or data flows in the “normal” operation. This process is enhanced by analyzing log data collected during runtime execution of the program against a policy to assign confidence values to the control and data flows. Using these confidence values, anomalous edges and/or paths with respect to the policy are identified to generate a “program execution” provenance graph associated with the policy.

Abstract: A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

A force-measuring and touch-sensing system includes piezoelectric force-measuring elements (PFEs) and piezoelectric ultrasonic transducers (PUTs), wherein each PUT can be configured as a transmitter (PUT transmitter) and/or a receiver (PUT receiver). The force-measuring and touch-sensing system is configured at a sense region. Each PUT transmitter transmits ultrasound signals towards the sense region and voltage signals are generated at the PUT receivers in response to ultrasound signals arriving from the sense region. Voltage signals are generated at PFEs in response to a low-frequency mechanical deformation of the respective piezoelectric capacitors. An event is determined to be a first-type touch event or a second-type touch event depending on a PUT data decrease and a magnitude of PFE data.
