The present disclosure may relate to a computer readable medium containing instructions that include obtaining a first signal corresponding to an idler roller guide speed, obtaining a second signal corresponding to a tire speed, and obtaining a third signal corresponding to a motor speed. The instructions may also include comparing the idler roller guide speed to an idler threshold based on a relationship between the idler roller guide speed, the tire speed, and the motor speed and comparing the motor speed to a motor threshold based on the relationship. The instructions may additionally include, based on one or both of the idler roller guide speed exceeding the idler threshold and the motor speed exceeding the motor threshold, determining that a slippage has occurred, and in response to the slippage, initiating a corrective action.

Intervertebral implant (1) comprising (i) a first elongated implant member (20) with a longitudinal axis (221), an upper surface (222) and a lower surface (223) for apposition to the endplates of two adjacent vertebrae, and with a lateral circumferential surface (224) and (ii) a second elongated implant member (30) with a longitudinal axis (321), an upper surface (322) and a lower surface (323) for apposition to the same endplates and with a lateral circumferential surface (324). Said elongated implant members (20, 30) are rotatably coupled to a central body (10) for rotation in a central plane (101 essentially parallel to said upper and lower surfaces. Further, a) said first and second elongated implant members (20, 30) comprise each an inner end portion (225;325) which comprises a segment of a toothed wheel (220;320) with gear teeth (23;33) and with an axis of rotation (227;327) essentially orthogonal to the central plane of the intervertebral implant; and a free outer portion (226;326); and whereby said free outer portions (226;326) of said first and second elongated implant members (20, 30) are rotatable around the axis of rotation (227;327) of the segment of a toothed wheel (220;320) of their respective inner end portions (225;325).

The present application relates to an expandable spinal implant assembly (1) for insertion between two adjacent vertebral bodies. The expandable spinal implant assembly comprises a first body (10) with a first superior endplate (11) and a first inferior endplate (12). The first superior endplate (11) and the first inferior endplate (12) are connected together on at least one side. Further, at least one strut (17) is comprised by said first body (10) and connects with one of said endplates, said strut (17) comprising a first threaded through bore (18) with a central axis. The expandable spinal implant assembly further comprises a substantially hollow second body (40) with a second superior endplate (41) and a second inferior endplate (42), said second body (40) being at least partially engaged within said first body (10). A central screw (70) with a first end comprising a ball-head (72) and a drive, said central screw (70) further having a threaded shaft (74) is engaged within said first threaded through bore (18). At least one track is arranged on a second top inside face of said second superior endplate (41) and/or on a second bottom inside face of said second inferior endplate (42), said at least one track being oriented at an acute angle relative to the central axis of said first threaded through bore when said substantially hollow second body (40) is at least partially engaged with said first body (10) and wherein said ball-head (72) of said central screw (70) is engaged into said at least one track.
摘要:
A method for an autonomous vehicle to follow a target is provided. The method may include obtaining a trajectory point of a target being followed by an autonomous vehicle, the trajectory point being determined based on a location that the target crossed a circle extending a first radius from a previous trajectory point along a path traversed by the target. The method may also include obtaining path restriction data indicating a location not to be traversed by the autonomous vehicle and when the trajectory point is located in the location not to be traversed by the autonomous vehicle, determining trajectory points around the location not to be traversed. The method may also include determining a path distance between the target and the autonomous vehicle based on distances between the trajectory point and the determined trajectory point and adjusting a velocity of the autonomous vehicle based on the determined path distance.

摘要:
The application relates to a bone screw assembly for fixation into a bone, comprising a first screw element with a body including a threaded first end with a first external screw thread having a first handedness and a first lead length. The first screw element comprises an internal thread feature with a second handedness and a second lead length located within a bore within said body. The screw assembly includes a second screw element comprising a second external screw thread with the second handedness and the second lead length. Said second screw element is arranged within said bore and said second external screw thread is engaged with said internal thread feature. The second screw element is movable from a first implantation configuration where the second screw element is arranged completely within said bore and a second implantation configuration where the second screw element protrudes from said bore.
