Patent number: 8516537Abstract: A downstream bandwidth conditioning device includes a forward path. A coupler is connected within the forward path providing a secondary path. A tuner connected to the coupler is tunable based on an input from a microprocessor. The tuner provides a tuner output of a selected channel, the selected channel being at least one high frequency channel and one low frequency channel. A channel analyzer connected to an output of the tuner provides the microprocessor with a modulation output that differs when the selected channel is an analog modulation versus a digital modulation. A slope adjustment circuit connected within the forward path between the coupler and the supplier side connector is adjustable based on an slope control output provided by the microprocessor. An output compensation circuit connected within the forward signal path between the coupler and the supplier side connector is adjustable based on a level control output from the microprocessor.Type: GrantFiled: October 9, 2009Date of Patent: August 20, 2013Assignee: PPC Broadband, Inc.Inventors: David Kelma, Tab Kendall Cox

Patent number: 8385219Abstract: A measurement device is provided for measuring an upstream bandwidth. The measurement device includes a return path extending at least a portion of a distance between a supplier side connector and a user side connector. A coupler is connected within the return path, the coupler providing a secondary path. A detection circuit is connected electrically downstream the coupler. A level detector is connected electrically downstream the detection circuit, and a microprocessor is connected electrically downstream the level detector. The microprocessor includes a first buffer and a second buffer.Type: GrantFiled: October 9, 2009Date of Patent: February 26, 2013Assignee: John Mezzalingua Associates, Inc.Inventors: David Kelma, Tab Kendall Cox

Publication number: 20110085586Abstract: A device for conditioning a total bandwidth includes a return path extending at least a portion of a distance between a supplier side connector and a user side connector, and a forward path extending at least a portion of a distance between the supplier side connector and the user side connector. An upstream section including a variable signal level adjustment device connected within the return path. A downstream section including a forward coupler connected within the forward path. The device further includes at least one microprocessor. The microprocessor is connected electrically upstream the variable signal level adjustment device. The microprocessor reduces an amount of signal level adjustment applied to the return path in response to a reduction in a level of a downstream bandwidth at the forward coupler.Type: ApplicationFiled: October 9, 2009Publication date: April 14, 2011Applicant: John Mezzalingua Associates, Inc.Inventors: David Kelma, Tab Kendall Cox

Publication number: 20100046226Abstract: A light fixture includes a member having a substantially frusto-conical shape. A channel extends between a wide top end of the member and a narrower bottom end of the member. The member includes multiple surfaces (“facets”) disposed around its outer surface. Each facet is configured to receive one or more light emitting diodes (“LEDs”) in a linear or non-linear array. Each facet can be integral to the member or coupled to the member. The channel is configured to transfer heat generated by the LEDs through convection. Fins can be disposed within the channel, extending from the inner surface of the member to an inner channel. The fins are configured to transfer heat away from, and provide a greater surface area for convecting heat away from, the member. For example, one or both of the channels can transfer heat by a venturi effect.Type: ApplicationFiled: June 18, 2009Publication date: February 25, 2010Applicant: Cooper Technologies CompanyInventors: Tab Kendall Cox, Susan Marie Orzell, Scott D.
