  • Patent number: 8297980
    Abstract: A calf roping training apparatus incorporating a simulated calf, a support column and a towing structure. The support column has a spin joint and an invert joint. The calf body of the simulated calf is formed by one or more pieces of simulated skin and a simulated head fixed in anatomical form by a body frame. The support column is anchored to the towing structure. The towing structure has a tow member, a pair of long skids, a short skid, and a towing attachment device. The support column base is attached to the short skid which provides for transfer of the weight of the simulated calf to the ground. The support column top is attached to or integrated with the body frame.

  • Patent number: 8091308
    Abstract: An improved dry stack insulated building block and block wall system, the block having a first and a second side wall, a central web interposed between the side walls, a pair of end transverse webs, and a pair of intermediate transverse webs. The side walls, central web, and transverse webs define a first, a second, and a third cell. A first cell core, second cell core, and a pair of third cell cores of insulative material are inserted in the respective cells. The cell cores have trapezoidal shaped ear members which matingly fit in notches in the transverse webs, the trapezoidal shaped ear members providing for the creation of a notch gap between the base of the ear members and the notch bottom of the respective notches, thereby accommodating crumbing in the notch bottom.

  • Patent number: 8047435
    Abstract: A secured electronic system and method for taking and counting votes. A database of unique ballot security codes, each ballot security code consisting of a ballot code representing the ballot selections of a voter and a security code derived from sensing with a biometric sensor a biometric presentation of a biometric feature of the voter. Each ballot security code is checked before entry into the database to verify that the security code component is not within a voter template of the security code component for any prior ballot security code, to prevent multiple votes being cast by any voter. Recounts are validated by verifying the uniqueness of the security code component of each ballot security code and verifying that each security code is not within a voter template of any other security code. Each ballot security code may also be checked against a registration data base thereby verifying that the voter is registered.

  • Patent number: 7648441
    Abstract: A self-contained, real-time self-use gait therapy device with a gait sensor, actuator, output speaker, and battery receptacle enclosed in a component case with a belt clip. Based upon step duration, step impact force, or step form data generated by the gait sensor, the actuator drives the speaker, producing beeps on a real-time basis with the pitch of each beep being a function of the step duration, step impact force, or step form for each step of the user. The speaker output is monitored and used by the user on a real-time basis to modify and improve his or her gait.
