David Thomas Brown 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).

  • Publication number: 20150360043
    Abstract: A wearable defibrillation system includes an output device and a motion sensor. The output device emits a sound or a vibration for the patient, who responds by deliberately tapping the system. The motion sensor registers the tapping, and interprets it as a reply from the patient. The reply can be that the patient is conscious, or convey data that the patient enters by tapping the right number of times, or that the patient wants attention, and so on. Since the patient does not need direct access to the wearable defibrillation system for tapping it, he or she can wear it under their other garments, which helps preserve their dignity and privacy.

  • Publication number: 20140100622
    Abstract: A medical device such as an external defibrillator delivers electrical therapy using a special pulse sequence. The special pulse sequence includes a defibrillation shock that is automatically followed by a quick succession of automatic post-shock anti-tachycardia (APSAT) pacing pulses. Because of the pacing pulses, the defibrillation shock can be of lesser energy than an equivalent defibrillation shock of a larger energy. Accordingly, the external defibrillator can be made physically smaller and weigh less, without sacrificing the therapeutic effect of a larger external defibrillator that would deliver a defibrillation shock of higher energy. As such, the defibrillator is easier to configure for transporting, handling, and even wearing.

  • Publication number: 20130225972
    Abstract: A medical device and/or a method are used by a rescuer who is caring for a patient. The depth of CPR chest compressions is determined, by detecting magnetic fields. An interference is sensed, which is not associated with the CPR chest compressions, but which is superimposed on the detected magnetic fields. Appropriate countermeasures may be taken, if the sensed interference is larger than a threshold.

  • Patent number: 6985480
    Abstract: A framework system serves to translate calls between dissimilar networks. More specifically, the framework system serves to translate calls between dissimilar packet networks and/or between a packet switch network and the public switched telephone network. The system includes a media engine module for terminating and handling channels of data transmitted between the networks in real time. An administrator module provides control and management interfaces for controlling processing applied to each channel. A conduit module serves to enable the distribution of software throughout the framework system allowing the distributed software to use interprocessor communication mechanism in the system. Optionally, a signaling engine module serves to provide access to call control information for connection between two networks.

  • Patent number: 6090756
    Abstract: The present invention provides compositions and methods for the coating and/or ballistics conditioning of firearm projectiles and firearm components including gun barrels, firearm chambers, fully assembled cartridges, shot gun shells, shotgun wads, shot capsules and sabots with molybdenum disulfide. The composition comprises powdered molybdenum disulfide suspended in a carrier comprising a volatile solvent and a binder selected from cellulosic-, alkyd- and acrylic-resins. Methods for the conditioning of firearm bores by the formation of a hardened layer comprising a product of the reaction or interaction of molybdenum disulfide with materials in the barrel bore are also disclosed.
