A differential dissecting instrument for differentially dissecting complex tissue is disclosed. The differential dissecting instrument comprises a handle and an elongate member having a first end and a second end, wherein the first end is connected to the handle. The differential dissecting instrument comprises a differential dissecting member configured to be rotatably attached to the second end and further comprises at least one tissue engaging surface. The differential dissecting instrument comprises a mechanism configured to mechanically rotate the differential dissecting member around an axis of rotation, thereby causing the at least one tissue engaging surface to move in at least one direction against the complex tissue. The at least one tissue engaging surface is configured to selectively engage the complex tissue such that the at least one tissue engaging surface disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

Methods and devices for soft tissue dissection

Methods and devices for blunt dissection include a drive mechanism comprising an elongate rotary drive train having a first proximal end connected to a mounting base for attaching to a handle or a surgical robot and a second distal end. The drive mechanism comprises a differential dissecting member (DDM) configured to be rotatably attached to the second distal end. The drive mechanism further comprises a mechanism configured to mechanically rotate the DDM about a substantially transverse axis of member rotational oscillation, thereby causing at least one tissue engaging surface to move in at least one direction against complex tissue and selectively engage the complex tissue such that when the DDM is pressed into the complex tissue, the at least one tissue engaging surface moves across the complex tissue and disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

A portable, configurable obstacle course game is provided for creating an interactive, entertaining game in a small space. The game is arranged along or above a path for a rolling ball, and obstacles move into and out of the ball's path, creating challenges for the players to roll or hit the ball through the path. Players can interact with each other and set difficulty levels in various play modes. The game is portable and configurable, so that it can be arranged on different playing surfaces, with different obstacles and even environmental interactions. The game can also communicate with wireless devices such as an application on a user's mobile phone, for additional game features.

Surgical instrument handle

An instrument for differentially dissecting complex tissue is disclosed, comprising a handle, a central longitudinal axis, and an elongate member, with a differential dissecting member (DDM) configured to be rotatably attached to a distal end. The DDM comprises at least one tissue engaging surface, a first torque-point disposed to a first side of an axis of rotation, and a mechanism configured to rotate the DDM around the axis of rotation, causing the tissue engaging surface to move in at least one direction against the complex tissue. The mechanism comprises at least one force-transmitting member attached to the first torque-point member and to a motive source configured to oscillate the DDM. The tissue engaging surface is configured to selectively engage the complex tissue such that it disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

A method for operating a submersible vehicle includes, responsive to detection of a vortex ring undesirably affecting the vehicle and/or at least one vehicle condition indicating the presence of a vortex ring undesirably affecting the vehicle, initiating at least one control action to mitigate the effect of the vortex ring on the vehicle.

A singulating and counting device includes a bulk housing for storing a plurality of substantially identical articles, an exit channel, and in the exit channel, forwardly- and rearwardly-directed jet apertures, each of which is fluidly connected to a positive pressure source. A forwardly-directed jet generated by the positive pressure source through the forward jet aperture can accelerate singulated articles in the exit channel, thereby increasing the interval between individual articles and rendering them more easily and accurately counted. A rearwardly-directed jet generated by the positive pressure source through the rearwardly-directed jet aperture can cause articles in the exit channel to return to the housing. A controller operatively connected with the pressure source(s) selectively controls the application of positive pressure to the aforementioned apertures to induce or halt singulation of the articles; the controller may be operatively associated with a sensor that detects and counts articles passing through the exit channel.

A submersible vehicle for use in a body of liquid includes a vehicle body, a pair of fins coupled to the vehicle body on opposed sides thereof, and a dihedral angle control system. The dihedral angle control is system operative to vary a fin dihedral angle of each of the fins.

Devices for navigating in a fluid medium having a solid boundary include a vehicle body and a fin attached to the vehicle body. The fin is configured to oscillate relative to the body such that interaction between the fin and the fluid medium produces propulsive forces that propel the vehicle body in a desired direction in the fluid medium. The fin is also configured to rotate relative to the body along a transverse axis such that engagement between the fin and the solid boundary propels the vehicle body in a desired direction on the solid boundary.
