Abstract: The present invention provides a system and method for measuring an impedance of one or more target cells before and after an electroporation protocol has been applied to the one or more target cells. The result of the impedance measurement provides a feedback control that can be implemented during and/or after the electroporation protocol to customize the electrical treatment for a particular target cell or cellular tissue.

Abstract: A power application device (PAD) (10) designed to operate in combination with a four-wheeled vehicle (110) such as a skateboard (112). The PAD (10) includes an attachment tube (12) having a front end (14) and a rear end (16). Between the front and rear ends (14,16) are located a front body support (32) and an optional rear body support (38). To the front end (14) of the attachment tube (12) is attached a handle bar (22) and to the rear end (16) is attached a drive wheel (90). The drive wheel (90) is rotated by a drive-wheel powering means (40) that consists of either a d-c motor (50) or an internal combustion engine (80). The motor (50) or engine (80) is operated respectively by a variable resistor (56) or a throttle control (86) located on the handle bar (22). To operate the PAD (10) a rider stands on the skateboard (112) and the PAD (10) is activated causing the drive wheel (90) to rotate, thereby causing the PAD (10) to move forward in unison with the skateboard (112).

Abstract: A magnetic brush development station includes, a housing forming a reservoir for developer materials. A plurality of augers are located in the housing for mixing developer material. A development roller is mounted within the housing for delivering developer material from the reservoir to a development zone. The development roller includes a core magnet inside a shell, having relative rotation. The core magnet extends less than the entire length of the development roller such that a developer nap on the shell does not extend to the respective ends. A metering skive controls the quantity of developer material delivered from the reservoir. A metering skive is positioned parallel to a longitudinal axis of the development roller at a location upstream in the direction of shell rotation prior to the development zone. A magnetic seal is located in association with the skive at each end to substantially prevent leakage of developer material.

Abstract: A magnetic brush development station for a reproduction apparatus. The magnetic brush development station includes a housing forming, at least in part, a reservoir for developer material; a plurality of augers located in the housing for mixing developer material within the reservoir; a development roller mounted within the housing for delivering developer material from the reservoir to a development zone; and a pressure equalization seal associated with the housing. The pressure equalization seal is placed over a hole defined in the housing, the pressure equalization seal allowing air flow, caused by pressure differential between inside the housing and the exterior thereof, through the seal without carrying developer material dust out of the housing.

The gaming apparatus includes a game controller adapted to control the outcome of a game played on the gaming machine for display on the display device. A player interface is coupled to the gaming apparatus and is configured to input information data personally identifying a player operating the gaming machine. This personal identification data, such as a players name, birthdate, digitized facial pictures of player, etc., is then integrated into the game for integral display in the game outcome on the display device. Thus, player interaction is increased by customizing the game screen presentation to include their personal information.

Abstract: A development station for an electrostatographic reproduction apparatus wherein pigmented marking particles from a particulate material mixture of pigmented marking particles and magnetic carrier particles are utilized to develop latent image charge patterns on a dielectric member. The development station has a housing adapted to be located adjacent to a dielectric member. The housing defines a reservoir for a particulate material mixture, and an opening facing such dielectric member. A mixer for mixing particulate material, a magnetic brush for applying pigmented marking particles from such particulate material mixture to a latent image charge pattern to develop such charge pattern, and a transport for transporting such particulate material from the mixer to the magnetic brush are located within the housing. A device is provided for collecting contaminating airborne particulate material contamination. The contamination collecting device includes an elongated tube, located externally of the housing.
