Derek S. Johnston has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Power supply and interconnect detector system
    Patent number: 7009521
    Abstract: A contactless ambient condition detection system includes at least one base connectable to a power and signal transmitting cable and a compatible detector. The detector removably engages the base. Electrical energy, from the cable is wirelessly coupled to the detector via the base. The detector is in wireless bidirectional communication with the base. Alarm indicating signals, generated remotely, can be wirelessly coupled, from the cable via the base, to the detector. Locally generated alarms can be wirelessly coupled to the cable. Detectors can be replaced without exposing the installer to AC contacts.
    Type: Grant
    Filed: October 2, 2001
    Date of Patent: March 7, 2006
    Assignee: BRK Brands, Inc.

  • Modular detector system
    Publication number: 20040257226
    Abstract: A modular detector includes at least one module receiving port. Members of a plurality of modules have a common form factor and are removably insertable into the port. Members of the plurality, when inserted, implement a selected communication, sensing or output function. One module can be removed and replaced with another thereby changing detector characteristics. A respective detector could have several ports to receive a plurality of insertable modules.
