7688560, Mar 30, 2010

Filed:

Mar 22, 2007

Appl. No.:

11/689691

Inventors:

Thomas Bruce Meagher - Houston TX, US
Kenneth John Murphy - Henderson NV, US
Linda M. Murphy, legal representative - Henderson NV, US

Assignee:

ICS Triplex Technology Limited - Essex

International Classification:

H02H 3/00

US Classification:

361 79

Abstract:

This invention relates to overload protection for a circuit driving a direct current (DC) load. The invention provides a method of generating an overload condition for an output module driving a load having a load current and a load voltage comprising the steps of: monitoring the load current at sample intervals; comparing the monitored load current to a predetermined load current threshold; starting an overload timer in the event that the timer is not running and the monitored load current is greater than said load current threshold; monitoring the load voltage at said sample intervals; generating a ramped load voltage waveform for reference purposes in dependence upon an initial load voltage and a predetermined step size load voltage in the event that the overload timer is running; generating an overload condition in the event that the monitored load voltage is less than said ramped load voltage reference waveform, the ramped load voltage is less than a predetermined positive ramp limit and the overload timer is running.

International Classification:

G01R 35/04

US Classification:

702106

Abstract:

This invention relates to line frequency synchronisation for use in diagnostics for alternating current electrical circuits. The invention provides a method of synchronising measurement system frequency with an alternating current line frequency comprising the steps of: adjusting the frequency of the measurement system frequency using a frequency locked loop until the measurement system frequency is within a predetermined range of said alternating current line frequency; and when the measurement system frequency is within a predetermined range of said alternating current line frequency adjusting the phase and the frequency of the measurement system frequency using a phase and frequency locked loop.

International Classification:

G06Q 30/00

US Classification:

705 14

Abstract:

A method for displaying a plurality of mattresses according to a color scheme is provided. The method includes categorizing a plurality of mattresses into at least three different types based on features of the mattresses other than size (e.g., based on comfort or style), designating a different color for each type of mattress, and displaying each of the mattresses with the designated color, or an article having the designated color, for the particular mattress type. For example, the article may include a pillow and/or foot protector having the designated color displayed prominently for a customer's reference. The method may further include grouping at least a portion of the mattresses together within the showroom based on the type of mattress, and displaying one of each type of mattress in a common region (e.g., a comparison center) for side-by-side comparisons of the different types of mattresses by customers.
