Abstract: An implantable medical device includes a case having a conductive housing defining an opening. A dielectric material is coupled to the conductive housing to hermetically seal the opening. A header block is coupled to the case over the dielectric material. An antenna is within the case under the dielectric material and there is no antenna feedthrough extending through the case into the header block.

Abstract: An implantable medical device may include a case which houses components of the implantable medical device. The implantable medical device may include an inductive coil coupled to a rechargeable battery. The inductive coil may be operative to inductively couple to an external coil and to transfer energy from the external coil to the rechargeable battery to recharge the rechargeable battery. The implantable medical device may include a cutout formed in the case of the implantable medical device and filled with a dielectric material. The cutout may be operative to reduce eddy currents in the case during recharge of the rechargeable battery. The implantable medical device may include a slot antenna disposed within the case. The slot antenna may be operative to communicate with an external device through the cutout in the case.

Abstract: A particular method of providing power to an implantable medical device includes providing a first signal to a primary coil that is inductively coupled to a secondary coil of an implantable medical device. The method also include determining a first alignment difference between a voltage corresponding to the first signal and at least one of a current corresponding to the first signal and a component voltage at a component of a primary coil circuit. The method further includes determining a frequency sweep range based on the first alignment difference. The method also includes performing a frequency sweep over the frequency sweep range.

Abstract: A system and method for displaying complex scripts with a cloud computing architecture may include a client device and a cloud computing server. The client device accesses a web application via the internet and transmits a request containing complex scripts to the cloud computing server. The cloud computing server parses the text and breaks the text down to a sequence of characters of a particular script, and maps the Unicode of each character to a particular glyph to obtain a glyph ID for each character making a one to one relationship. The cloud computing server analyzes each character, assigns, and applies specific font related operations to each glyph. The cloud computing server optimizes and compresses the glyph ID and positioning data, and transmit the compressed data back to the client device to be rendered on the display of the client device.

Abstract: A novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern is disclosed. The process requires only bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern, Kainite is converted to schoenite with simultaneous removal of NaCl by processing it with water and end liquor obtained from reaction of schoenite with MOP for its conversion to SOP. The end liquor from kainite to schoenite conversion (SEL) is used for the recovery of MOP. SEL is desulphated and supplemented with MgCl2 using end bittern generated in the process of making carnallite. The carnallite is decomposed to get crude potash which in turn processed to get MOP. The carnallite decomposed liquor produced in the decomposition of carnallite is reacted with hydrated lime for preparing CaCl2 solution and high purity Mg(OH)2 having low boron content, The CaCl2 solution is used for desulphatation of SEL producing high purity gypsum as a byproduct.

Abstract: The present invention relates to recovery of industrial grade potassium chloride and low sodium edible salt from bittern as part of an integrated process. The process comprises, mixing low sulphate concentrated feed bittern (a by-product of salt industry) of density 31.5 to 32.5° Be (sp.gr. 1.277-1.289) with high density end bittern of density 36.5 to 37.5° Be? (sp.gr. 1.336-1.35), thereby producing low sodium carnallite, from which industrial grade potassium chloride is produced. The resultant bittern is evaporated in forced evaporation system, thereby producing crude carnallite, from which low sodium salt that would be beneficial to persons suffering from hypertension is produced. When sulphate-rich bittern is used, such bittern is desulphated with CaCl2 that is generated from carnallite decomposed liquor through reaction with lime, and wherein low B2O3-containing Mg(OH)2 is a by-product. The entire content of potassium in feed bittern is recovered in the process of the invention.
