Publication number: 20240112574Abstract: 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.Type: ApplicationFiled: October 3, 2023Publication date: April 4, 2024Inventors: Mark J. MORAN, James MARTIN, James CONLAN, Richard W. KELLEY, II, Steven B. LANE, Alexander J. PALUMBO, Marcus N. SCHMIDT, Joseph M. CALDWELL

Patent number: 7479824Abstract: A dual mode voltage supply circuit (50) includes an active mode voltage supply circuit (58) and a passive mode voltage supply circuit (60). The active mode voltage supply circuit (58) is selectively operative to supply a voltage (57) based on mode control information (22). The active mode voltage supply circuit (58) is operative to provide a first current capacity. The passive mode voltage supply circuit (60) is operatively coupled to the active mode voltage supply circuit (58). The passive mode voltage supply circuit (60) is operative to supply the voltage (57) when the active mode voltage supply circuit (58) is not supplying the voltage (57). The passive mode voltage supply circuit (60) is operative to provide a second current capacity that is less than the first current capacity.Type: GrantFiled: July 13, 2006Date of Patent: January 20, 2009Assignee: Freescale Semiconductor, Inc.Inventors: Michael L.
