Patent number: 8749159Abstract: An illumination system includes a master power supply providing power to several illumination modules. The master power supply is constructed and arranged to generate high-frequency and low-voltage electrical power provided to a primary wire forming a current loop. Each illumination module includes an electromagnetic coupling element and several light sources. The electromagnetic coupling element includes a magnetic core arranged to receive the current loop in a removable arrangement, and a secondary wire wound around the magnetic core to enable inductive coupling. The secondary wire is connected to provide current to the light sources that may be arranged in the illumination module as a DC load or an AC load.Type: GrantFiled: April 16, 2011Date of Patent: June 10, 2014Assignee: EMD Technologies IncInventor: Robert Beland

Patent number: 5326143Abstract: A refuse collecting device includes a frame configured with a longitudinal channel, an actuating member, a disposable container, and U-shaped retaining members. The actuating member is positioned within the channel and freely slides through the channel. The U-shaped retaining member releasably retains the disposable container to the actuating member. The disposable container is attached to the frame by sliding the container hinge over the U-shaped retaining member. After the container is attached, sliding the actuating member upward within the channel causes the container to close thereby picking up the refuse. The container is self-locking when closed and can be removed by sliding the container off the U-shaped retaining member.Type: GrantFiled: May 8, 1992Date of Patent: July 5, 1994Assignee: EMD Technologies, Inc.Inventor: Egon S.
