Abstract: There is provided a lighting system for illuminating an optically translucent panel, the panel having an exposed surface, a first edge, and a second edge opposite the first edge. The lighting system comprises a light source having a light-emitting surface, and an optical device configured to be positioned on the exposed surface of the panel adjacent to the first edge, the light-emitting surface of the light source configured to be positioned on the optical device at a non-zero angle relative to the exposed surface of the panel, the optical device configured to direct light emitted by the light-emitting surface into the panel, the light guided within the panel towards the second edge by total internal reflection.

Abstract: A device for removing weeds from a lawn or garden surface comprising: a drive shaft having a first end configured to operatively couple to a power unit for rotation about a longitudinal axis of the drive shaft and a second, free distal end; coupled to the second end, an auger having one or more flights and a boring member; and a weed engagement member axially coupled to the drive shaft at a longitudinal position intermediate the auger and the first end. A base member of the weed engagement member has at least one grasping finger depending therefrom towards the auger and axially offset from the longitudinal axis. Rotation of the drive shaft in a first direction when the boring member is in contact with the surface moves the auger into engagement with the weed and the weed engagement member is drawn towards and into engagement with the weed and vice-versa.

Abstract: Described are lawn mowers/autosensing modules for lawn mowers configured to engage and/or disengage a drive motor based on one or more of: a tilt angle relative to a direction of travel, rotations of at least one wheel, applied load, a tension and a lawn mower position. The lawn mowers may comprise: a cutting blade(s); a blade motor operatively connected to the cutting blade(s); a drive motor operatively connected to a wheel assembly; a tilt sensor configured to sense a tilt angle of the lawn mower; and a controller operatively connected to the drive motor and in communication with the tilt sensor, and configured to disengage the drive motor in response to receiving a disengage signal, without disengaging the blade motor. When the tilt sensor senses the tilt angle is at or above a disengage angle, the tilt sensor transmits the disengage signal for receipt by the controller.

Abstract: Described herein are self-propel accessories for walk behind/push-driven machines/devices comprising: drive assembly motor(s) operatively connected to at least one power supply; at least one drive assembly for imparting drive from the drive assembly motor(s) to at least one accessory wheel assembly that is operatively connected to an output shaft of the drive assembly motor(s) and one of an axle or a drive engagement surface of the at least one accessory wheel assembly having accessory ground engagement wheel(s) coupled to at least one end of the axle for rotation therewith; a controller for the drive assembly motor(s) having an actuator for engaging the drive assembly motor(s); and an attachment assembly for coupling the drive assembly motor(s), the at least one drive assembly and the at least one accessory wheel assembly to a housing of the push-driven machine or device in place of a wheel assembly/sub-assembly of the push-driven machine or device.

Abstract: Snow removal machines are provided that have an auger assembly for directing snow rearwards to be received by a discharge chute, and an auxiliary snow moving assembly for directing snow rearwards to be received by the discharge chute. The auger assembly has auger blade(s) coupled to an auger axle for rotation therewith about a first axis defined by the auger axle. The auxiliary snow moving assembly has snow moving member(s) coupled to an auxiliary axle for rotation therewith about a second axis defined by the auxiliary axle. The auxiliary axle is lower and rearwards of the auger axle towards the discharge chute; and an auxiliary drive assembly is configured to rotationally couple the auxiliary axle to the auger axle such that rotation of the auxiliary axle is driven by rotation of the auger axle.

Abstract: A handle is attachable to a shaft, for example, of a shovel. The shaft extends lengthwise along a shaft axis. The handle includes a collar defining an opening to receive the shaft, the collar rotatable about the shaft axis; a transverse arm extending along a transverse axis from a first end to a second end opposite the first end, the transverse arm rotatably connected to the collar at the first end; and a grip extending from the second end of the transverse arm. The grip is rotatable about the transverse axis and may be selectively axially movable along the transverse axis.

Abstract: Described herein are snow removal machines having at least one auxiliary snow moving member. According to some embodiments, the snow removal machines comprise: an auger assembly for directing snow rearwards to be received by a discharge chute, the auger assembly having auger blade(s) coupled to an auger axle for rotation therewith about a first axis defined by the auger axle; an auxiliary snow moving assembly for directing snow rearwards to be received by the discharge chute, the auxiliary snow moving assembly having snow moving member(s) coupled to an auxiliary axle for rotation therewith about a second axis defined by the auxiliary axle, wherein the auxiliary axle is lower and rearwards of the auger axle towards the discharge chute; and an auxiliary drive assembly configured to rotationally couple the auxiliary axle to the auger axle such that rotation of the auxiliary axle is driven by rotation of the auger axle.

Abstract: Described herein are self-propel accessories for walk behind/push-driven machines/devices comprising: drive assembly motor(s) operatively connected to at least one power supply; at least one drive assembly for imparting drive from the drive assembly motor(s) to at least one accessory wheel assembly that is operatively connected to an output shaft of the drive assembly motor(s) and one of an axle or a drive engagement surface of the at least one accessory wheel assembly having accessory ground engagement wheel(s) coupled to at least one end of the axle for rotation therewith; a controller for the drive assembly motor(s) having an actuator for engaging the drive assembly motor(s); and an attachment assembly for coupling the drive assembly motor(s), the at least one drive assembly and the at least one accessory wheel assembly to a housing of the push-driven machine or device in place of a wheel assembly/sub-assembly of the push-driven machine or device.
