Patent number: 8761885Abstract: Apparatus and methods for estimating the remaining life of a battery in an implantable medical device (“IMD”) are disclosed herein. The terminal voltage of the battery is measured and the measurements create a baseline curve of the battery voltage depletion. The points along the baseline curve can be linearly extrapolated to calculate the voltage depletion rate, which can estimate the remaining life of the battery.Type: GrantFiled: April 29, 2011Date of Patent: June 24, 2014Assignee: Cyberonics, Inc.Inventor: Saadat Hussain

Patent number: 8680347Abstract: A high assay decabromodiphenylalkane product in which the alkylene group contains in the range of about 1-10 carbon atoms and has an occluded free bromine content of <500 ppm is prepared. The process comprises brominating, in a liquid phase reaction mixture, at least one ?,?-diphenylalkane having an alkylene group of 1-10 carbon atoms, with a limited excess of bromine, in the presence of an aluminum, aluminum halide or a ferric halide catalyst in which the original halogen atoms of such halides are chlorine atoms, bromine atoms, or both. The limited excess of bromine is such that the maximum excess amount of bromine used in conducting the reaction is about 20 mole % relative to the stoichiometric amount required to convert the amount of ?,?-diphenylalkane used to decabromodiphenylalkane. Crude high assay decabromodiphenylalkane product is prepared without use of heat treatment, oven ageing, or grinding or other forms of pulverization.Type: GrantFiled: July 15, 2010Date of Patent: March 25, 2014Assignee: Albemarle CorporationInventors: Saadat Hussain, Arthur G.

Patent number: 8577459Abstract: A method for estimating capacity of a battery in an implantable medical device includes obtaining a characteristic curve of voltage versus resistance for the battery, periodically determining voltage and resistance of the battery, and comparing the resistance with a third derivative function of the characteristic curve, the third derivative function having roots representing near depletion of the battery and end of service of the battery, respectively. Remaining time of service of the battery can also be determined by comparing the resistance value with a curve of battery capacity versus resistance for the battery.Type: GrantFiled: January 28, 2011Date of Patent: November 5, 2013Assignee: Cyberonics, Inc.Inventors: Anthony W.

Patent number: 8217207Abstract: High assay, reaction-derived decabromodiphenylethane product is prepared by feeding (i) diphenylethane or (ii) partially brominated diphenylethane having an average bromine number less than about two, or (iii) both of (i) and (ii), into the liquid confines of a reaction mixture. Such reaction mixture is (a) formed from components comprised of excess liquid bromine and aluminum-based Lewis acid bromination catalyst, and (b) maintained at one or more elevated reaction temperatures of from about 45°-90° C., and at least when elevated pressure is needed to keep a liquid state in the reaction mixture at the temperature(s) used, the reaction mixture is at such an elevated pressure, whereby ar-bromination occurs. The feeding is conducted at a rate slow enough to form high assay reaction-derived decabromodiphenylethane product, which is an effective flame retardant.Type: GrantFiled: August 5, 2011Date of Patent: July 10, 2012Assignee: Albemarle CorporationInventors: Saadat Hussain, Arthur G.
