US Patent:

6452966, Sep 17, 2002

Filed:

Jan 19, 2000

Appl. No.:

09/487072

Inventors:

Jeffrey Kaiser - Roselle IL
Daniel Ziemba - Carpentersville IL

Assignee:

Charles Industries, Ltd. - Rolling Meadows IL

International Classification:

H04B 1700

US Classification:

375228, 379 24, 37910005, 324 7611, 370252

Abstract:

An improved digital signal line carrier type detector non-conductively senses and counts voltage pulses on a probed line. Further, the detector produces a human-readable display of the carrier type in use on the probed line, and can detect carriers of various frequencies without the use of multiple oscillators or probes. The detector may be housed in a hand-held portable housing, and may be powered by one or more batteries. A timer circuit is usable with the detector to prevent accidental discharge of the battery for an extended period of time.

Appl. No.:

10/017799

Inventors:

Jeffrey Kaiser - Roselle IL, US
Daniel Ziemba - Carpentersville IL, US

International Classification:

H04M001/00
H04M009/00

US Classification:

379/399010, 379/413020

Abstract:

An improved telephone customer transmission line conditioner, method of making a line conditioner, improved build-out, method of making a build-out, and improved method of conditioning a line using the line conditioner and/or the improved build-out provide improved voice-band transmission as compared to a bare twisted pair, while also allowing the transmission of high-frequency digital signals, such as ADSL signals and other signals. The apparatus and method provide a boost in the high end of the voice-band (approximately 2 kHz to 3.4 kHz) to compensate for the roll-off normally located there in a bare cable, and also provide a substantial rise in the frequency response in a frequency range used for high-frequency digital transmissions. A notch in the response between frequency bands suppresses harmonic cross talk between bands.

Appl. No.:

12/901089

Inventors:

Jeffrey KAISER - Roselle IL, US
Joseph L. St. Romain - Fair Oaks Ranch TX, US
Joseph T. Charles - Jupiter FL, US

Assignee:

Charles Industries, Ltd. - Rolling Meadows IL

International Classification:

H02J 7/00

US Classification:

320107

Abstract:

A battery charger is provided. The charger includes an AC input for connection to a source of AC power and a plurality of DC outputs each being connectable to a battery bank. A user interface is provided for inputting battery information including battery voltage and battery type for each DC output. A main controller is in communication with the user interface and receives the battery information from the user interface. The main controller uses the battery information to provide independent charging instructions for each DC output. At least one power module is in communication with the main controller and receives the charging instructions from the main controller. The power module is configured to convert the AC power from the AC input to DC power and is selectively connectable with each of the plurality DC outputs. The power module is configured such that the charging instructions from the main controller direct the power module as to which DC output to connect and a charge voltage and a charge amps to be provided by the power module to that DC output.
