Abstract: The invention is a syringe pole device used to inject dangerous animals while operating the plunger of the syringe in and out from the rear of the pole. The invention consists of a specific size outer tube with a threaded fitting permanently attached on the front end. A specific diameter and length of inner tube with a specific size and shape knob permanently attached to the back of the tube serves as a push/pull knob. After inserting the inner tube through the outer tube, a specific size flat washer is affixed to the front of the inner tube by using a specific size sheet metal screw. A specific size plunger is stretched over the washer and a specific size syringe is slid over the plunger and twisted onto the threaded fitting that is attached to the outer tube, thus completing the syringe pole device.

Abstract: A device for transporting a human subject over a surface. The device is a dynamically balancing vehicle having a control loop for providing balance. The device includes a platform defining a fore-aft plane. The platform supports a payload including the human subject. A ground contacting module is included which may include one or more wheels. A ground-contacting member is movably coupled to the platform. The platform and the ground-contacting module form an assembly having a center of gravity that is defined with respect to the ground-contacting member and which includes any loads on the device. The device further includes a support. The support may be a seat for supporting the subject and the support is coupled to the platform in such a manner as to permit variation of the position of the center of gravity in the fore-aft plane by translation and rotation of at least a portion of the support. In one embodiment, translation and rotation of the seat of the device are mechanically coupled together.

Abstract: A transportation vehicle for transporting an individual over ground having a surface that may be irregular. The vehicle has a support platform for supporting the subject and the support platform is coupled to a ground-contacting module at a pivot. While the ground-contacting module may be statically stable, balance of the support platform with respect to the ground-contacting module is maintained by motion of the ground-contacting module in response to leaning of the support platform. A motorized drive coupled to the ground-contacting module causes locomotion of the vehicle and the subject therewith over the surface, while a control loop, in which the motorized drive is included, dynamically enhances stability in the fore-aft plane by operation of the motorized drive in connection with the ground-contacting module. In the event of failure of the control loop, the pivot connection of the support platform to the ground-contacting module may be locked, thereby ensuring stability of the static assembly.

Abstract: A class of transporters for carrying an individual over ground having a surface that may be irregular. Various embodiments have a motorized drive, mounted to the ground-contacting module that causes operation of the transporter in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered. Methods of controlling the transporter are described that allow the dynamic behavior of the transporter to more closely match preferences of a rider. These methods include providing preferential responsiveness to change in pitch angles and pitch rates.

Abstract: A method and apparatus that afford a user accelerated access to operation of a balancing personal transporter. The method includes first initializing a single-axis stabilizer, and, while initializing a 3-axis stabilizer, alerting the rider that the transporter is ready for use, allowing operation of the transporter, and then completing initialization of the 3-axis stabilizer, and employing the 3-axis stabilizer for control of the balancing personal transporter. Apparatus includes single axis and 3-axis stabilizer and means to alert the user of the personal transporter.

Abstract: Improvements to a motorized balancing personal transporter are revealed in embodiments of the invention. In one embodiment of the invention, a transporter for carrying a payload includes a platform for supporting a user; a ground-contacting module, to which the platform is mounted, which propels the user; a proximity detector for determining the presence of a user; and a safety switch coupled to the detector for inhibiting operation of the ground-contacting module unless the proximity detector has determined the presence of the user; and a motorized drive arrangement coupled to the ground-contacting module for causing automatically balanced and stationary operation of the device unless the proximity detector determines the presence of the user on the device. Various other mechanisms are provided for receiving rider input in order to direct steering of the transporter.

Abstract: A method for stabilizing a balancing transporter under riderless conditions. The balancing transporter is characterized by a center of mass, and has two laterally disposed wheels and a region of contact with an underlying surface. In accordance with the method, the absence of a user aboard the transporter is first detected. Then a desired transporter pitch is determined such as to establish a condition of stasis wherein the center of mass is disposed directly above the region of contact between the balancing transporter and the underlying surface. Finally, a torque is applied to the laterally disposed wheels so as to maintain the transporter at the desired transporter pitch. The torque may include coadded terms where the terms are, respectively, proportional to a pitch error, a pitch rate, a wheel rate, and an integral representing the wheel rotation that was required to bring the transporter to the condition of stasis.
