US Patent:

20120234629, Sep 20, 2012

Filed:

Mar 9, 2012

Appl. No.:

13/416034

Inventors:

Christopher E. PETERS - Nashua NH, US

International Classification:

E04G 1/34

US Classification:

182151

Abstract:

The invention is a support platform for providing a stable and secure work surface when the existing surface is irregular, such as open ground, or when the existing surface is inconvenient, such as a staircase. The support platform is configured to be transported by a single person, deployed for use, and taken down and stowed as needed. The support platform can be used for directly supporting a person, or can be used for supporting a tool, such as a ladder in a manner that provides secure and slip-resistant support. In some cases, the platform is larger and/or heavier and is transportable by multiple persons or with assistance selected from the group consisting of mechanical assistance, power assistance, and automation.

Abstract:

An apparatus for monitoring radio frequency (RF) signals is disclosed. The apparatus includes an RF splitter, a set of track-and-hold circuits, a set of analog-to-digital circuits (ADC) and a frequency tracking module. The RF splitter splits a set of incoming RF signals into multiple RF signal paths. Each of the track-and-hold circuits, which is clocked at a different frequency than others, samples the incoming RF signals from a respective one of the RF signal paths. Each of the ADCs receives the sampled data from a respective one of the track-and-hold circuits. Each of the ADCs is also clocked at same frequency as a corresponding one of the track-and-hold circuits. The frequency tracking module determines a frequency of the incoming RF signals.
