Abstract: Techniques are described for replacing a keypad of an existing security system within a property with a communication-enabled keypad device with dual functioning capabilities as a communicator device and a keypad device. In some implementations, data is received from a security panel of a property. A keypad bus protocol of the security panel is determined based on the data received from the security panel. Sensor data is received from one or more sensors located within the property. A monitoring system command that is not specified within a keypad bus of the security panel is determined based on based on the obtained sensor data. The monitoring system command is converted to a panel command using the keypad bus protocol. The panel command is transmitted on the keypad bus of the security panel.

Abstract: A shutter assembly includes a base plate defining a shutter opening having a central axis, and a drive assembly coupled to the base plate. The drive assembly includes a rotatable pinion gear, and a drive rack mating with the pinion gear and moveable in a substantially linear direction in response to rotation of the pinion gear. The shutter assembly also includes a plurality of shutter blades operably connected to the drive rack. The plurality of shutter blades are configured to rotate between an open position exposing the shutter opening and a closed position substantially occluding the shutter opening in response to movement of the drive rack in the substantially linear direction.

Abstract: A trolley assembly for overhead track testing is provided. In one example embodiment, a trolley assembly includes an idle roller that rotates about a first axis, a first top roller coupled to a first end of the idle roller via a first trolley upright support, and a second top roller coupled to a second end of the idle roller via a second trolley upright support. The trolley assembly includes a cantilever coupled to the idle roller. The trolley assembly includes a driveshaft coupled to a first end of the cantilever. The trolley assembly includes at least one motor coupled to the drive shaft.

Abstract: The present disclosure provides systems and methods to test an autonomous vehicle. In particular, the systems and methods of the present disclosure can receive, from one or more test nodes of a preconfigured test track, log data indicating positions of elements of the test track over a period of time. Log data indicating parameters of an autonomous vehicle over the period of time can be received from the autonomous vehicle. The log data indicating the positions of the elements of the test track over the period of time can be compared with the log data indicating the parameters of the autonomous vehicle over the period of time to determine a performance metric of the autonomous vehicle on the test track over the period of time.

Abstract: A joint compound sanding device (10) comprises a hand held housing (12) and a bottom plate (66) coupled to the hand held housing (12). The bottom plate (66) includes a plurality of dust collection apertures (74) extending through the bottom plate (66) between a vacuum manifold (64) and a bottom surface (76). A plurality of dust collection channels (78) are formed in the bottom surface (76) defining mesas (80) there between. The mesas support a porous joint compound sanding screen (54).

Abstract: A joint compound sanding machine imparting an oscillating motion on an abrasive within a sanding plane and on a removable abrasive extension comprises a hand held housing and an oscillating base. The base is coupled to the hand held housing by a motor. The base comprises a bottom surface defining the sanding plane, a clamp for securing the abrasive against the bottom surface, and a mounting for securing the removable abrasive extension to the base. The motor is coupled between the hand held housing and the base for imparting the oscillating motion, with respect to the hand held housing, on the base to oscillate both the abrasive and the removable abrasive extension.
