Appl. No.:

13/051683

Inventors:

Robert Siciliano - Boonton NJ, US
Daniel Scheffer - Boonton NJ, US
John Hayes - Hardwick NJ, US
John Petro - Florham Park NJ, US

Assignee:

ASCO POWER TECHNOLOGIES, L.P. - Florham Park NJ

International Classification:

H02B 1/24

US Classification:

307112

Abstract:

A method is provided and may include monitoring a transfer switch and determining an operating condition of the transfer switch based on the monitoring. The method may further include comparing by a processor the operating condition to a predetermined value, and determining a maintenance condition of the transfer switch based on the comparison.

Assignee:

Ohaus Scale Corporation - Florham Park NJ

International Classification:

G06F 1520
G01G 1314

US Classification:

364567

Abstract:

An electronic balance having a strain gauge transducer. The analog output signal of the transducer is processed digitally so that the displayed weight is based on several successive digitized analog signal samples. Various operating parameters (e. g. , conversion factors for several different units of weight) are stored in a non-volatile memory so that the scale can perform various weighing functions. The scale has a parts counter mode of operation requiring re-taring of the parts container whenever the scale is recalibrated for a different individual part weight.

Appl. No.:

15/902863

Inventors:

- Florham Park NJ, US
Daniel G. Scheffer - Boonton NJ, US

International Classification:

H02J 9/06
H02J 3/14
G01R 19/25

Abstract:

An example system for controlling a transfer switch includes a power modulation circuit and a control module. When the power modulation circuit is coupled to a solenoid of a transfer switch, a first power supply, and a second power supply, the control module is configured to perform functions. The functions include sensing one or more operating conditions of the system and using the one or more operating conditions of the system as a basis to determine one or more control parameters. The functions also include controlling, according to the one or more control parameters, the power modulation circuit to cause the second power supply to provide a current through the solenoid, thereby operating the transfer switch to discontinue a conductive path between a load and the first power supply and create a conductive path between the load and the second power supply.

Inventors:

- Florham Park NJ, US
Daniel G. Scheffer - Boonton NJ, US

International Classification:

A62C 35/68
F04D 15/00
A62C 37/00

Abstract:

Example devices, systems, and methods disclosed herein relate to a controller configured to control pressure maintenance in a fire protection system. A controller may be configured to control a fire pump to provide a first level of water pressure and to control operation of a jockey pump that is coupled in parallel with the fire pump to provide a second level of water pressure that is less than the first level. The controller is further configured to receive, from a pressure sensor coupled to the fire protection system, an output representative of the water pressure. The controller is configured to provide instructions to initiate the jockey pump based on a pressure value associated with the output being below a first value, and to provide instructions to initiate the fire pump based on the pressure value being below a second value that is less than the first value.

Appl. No.:

14/061810

Inventors:

Robert Siciliano - Boonton NJ, US
Daniel Scheffer - Boonton NJ, US

Assignee:

ASCO POWER TECHNOLOGIES, L.P. - Florham Park NJ

International Classification:

H02J 4/00

US Classification:

307 64

Abstract:

An automatic transfer switch (ATS) for supplying power to a load is provided. The ATS includes a main transfer switch portion configured to connect one of a first or second power source to the load. The ATS also includes a bypass transfer switch portion configured to form a bypass connection from either the first or second power source to the load. The bypass transfer switch portion includes (i) a first bypass switch configured to connect the first power source to the load upon closing of the first bypass switch and (ii) a second bypass switch configured to connect the second power source to the load upon closing of the second bypass switch. Further, the ATS includes a primary load connection connecting the main transfer switch portion to the load, where the primary load connection is formed at least in part by the first and second bypass switches.
