Abstract: Examples described herein involve a playback device performing one or more playback device actions based on locations of one or more physical contacts on an external surface of the playback device. A processor of the playback device may receive from an array of proximity sensors underlying an external surface of the playback device, location data indicating a physical contact at a location on the external surface. Based on at least the location, the processor may identify a playback device action from a plurality of playback device actions, and cause at least the playback device to perform the identified playback device action. The playback device may further include at least one orientation sensor from which the processor may also receive orientation data indicating an orientation of the playback device. The processor may identify the playback device action also based on the orientation of the playback device.

Abstract: An industrial mower sealed roller bearing system provides a roller bearing to avoid repeated and frequent repacking. The system includes an industrial mower having a roller mount and a ground roller. The ground roller bearing includes an insert body having a first end, a closed second end, and a channel extending into the first end towards the second end. An outer section of a shaft extends from the insert body and is couplable to the roller mount. A face seal is provided at the first end of the insert body to define a sealed interior chamber. The face seal is positioned relative to the insert body and the shaft such that the insert body is rotatable relative to the shaft. Each of a plurality of interior bearings is positioned within the sealed interior chamber of the insert body such that the insert body is rotatable relative to the shaft.

Abstract: Examples described herein involve a playback device having capacitive sensors. In an example implementation, an enclosure of a playback device includes: a first external surface comprising a speaker grille; a second external surface substantially orthogonal to the first external surface; and an array of capacitive sensors underlying the second external surface of the playback device. The array of capacitive sensors includes a first subset of capacitive sensors underlying a first region of the second external surface, a second subset of capacitive sensors underlying a second region of the second external surface, and a third subset of capacitive sensors underlying a third region of the second external surface. The enclosure and sensors may be arranged such that a particular side of the first region is adjacent to a first side of the second region, a particular side of the third region is adjacent to a second side of the second region.

Abstract: Examples described herein involve a playback device with an enclosure including a first external surface where out-ward facing speakers of the playback device are positioned and a second external surface substantially orthogonal to the first external surface, an array of proximity sensors underlying the second external surface of the playback device; and an orientation sensor. The playback device receives data user input, the user input comprising a first physical contact at a first location on the array of proximity sensors followed by a second physical contact at a second location on the array of proximity sensors; and in response to receiving the data, causes a playback volume of the playback device to change. The playback volume increases if the orientation sensor indicates that the enclosure is in a first orientation and decrease if the orientation sensor indicates that the enclosure is in a second orientation.

Abstract: A transport refrigeration unit (TRU) battery charging system includes a programmable transport refrigeration system (TRS) Controller, a TRU battery and a programmable battery charger (BC) programmed to transfer electrical current to the TRU battery via a predetermined current path through the programmable TRS Controller in response to a value of offset current drawn from the TRU battery by the programmable TRS Controller and subsequently communicated to the programmable BC by the programmable TRS Controller. The programmable TRU battery charger allows for a dynamic load characterization of the programmable IRS Controller and accessory loads based on programmable TRU battery charger internal shunt current measurements and programmable TRS Controller internal shunt current measurements to allow the programmable TRU battery charger to function properly with all intended modes of operation.

Abstract: A boom arm cutting disk device for using a full area of a boom arm mounted cutting disk to cut materials facilitating vertical cutting and mulching of trees, brush, or the like. The device includes a disk configured for mounting on a boom arm such that the disk is rotatable relative to the boom arm. Each of a pair of cutters is coupled to and extends from the disk. Each of the cutters has a respective interior side edge aligned with a center of the disk and a respective blade edge extending outwardly from the interior side edge. Each blade edge defines a leading edge of the cutter as the disk is rotated wherein the cutters are configured to cut material by contact with the leading edges as a central area of the disk is urged towards the material while the disk is rotated.

Abstract: A shearable drive coupling assembly includes an adapter having a top end with a drive shaft well extending downwardly therein. A plurality of spindle splines extends outwardly from an outer surface of the adapter and a plurality of shaft splines extends inwardly from an inside surface of the adaptor. The plurality of spindle splines engage a receiver of an article of powered equipment. A drive shaft of a drive motor engages the shaft splines so that the adapter is coupled to the drive shaft and transfers a rotational torque between the drive shaft and the receiver. The plurality of spindle splines or the plurality of shaft splines shears away from the adapter to decouple the drive shaft from the receiver when the receiver is exposed to a trigger counter-rotational force to protect the receiver and the drive shaft from damage.

Abstract: In an embodiment, a stepped spring contact may have a first portion, a transition portion, and a second portion. The first portion may include a plurality of windings whose pitch may vary. The second portion may include a plurality of windings that are closely wound. A pitch of the windings contained in the second portion may be, for example, constant. The transition portion may include a winding that may make mechanical and electrical contact with a first electrical conductor (e.g., a pad contained on a printed circuit board (PCB)). The first portion may include a tip. The tip may be, for example, flat shaped or conically shaped. The tip may make electrical contact with a second electrical conductor (e.g., a terminal connector). In operation, the stepped spring contact may provide electrical continuity between the first electrical conductor and the second electrical conductor.
