Abstract: A parking enforcement device can be secured to a surface adjacent to the area designated as NO PARKING. The enforcement device can include an elongated hollow body, a window provided to the tubular body, a battery, an internal frame assembly disposed inside of the elongated hollow body, and a camera disposed inside of the elongated hollow body. The internal frame assembly defines a cavity in which the battery is located. A camera support pole extends vertically upwards from the internal frame assembly. The camera is secured to the camera support pole and located vertically along the camera support pole such that the camera views outward through the window. A solar panel can be provided atop the parking enforcement device to recharge the battery.

Abstract: This invention discloses a method for the simultaneous control and management of an arbitrary number of bubble memories, whereby the existence, locations, and defects of the blemished data positions in the bubble memory devices are managed by the invention, allowing the external device using the bubble memories to no longer be cognizant of the blemished data positions of the bubble memories. Specifically, this invention uses a shift register connected in a parallel manner to the bubble memories, a second shift register connected to the external data bus, a means for storage for the valid data positions in the bubble memory devices, and a means for gating data between the two shift registers in a serial manner, the gating means being controlled by the memory containing the valid data positions.
