Publication number: 20240126461Abstract: Techniques are provided for block-level fail atomicity on byte-level non-volatile media. In one technique, an offset table and application data that stores content of a file are stored for a file. The offset table includes multiple entries, each entry being associated with a different offset value and storing a logical block address (LBA) that references a location in the application data. In response to receiving a request, that includes an input buffer and an offset value, to update the file: (a) an entry, in the offset table, that corresponds to the offset value and comprises a first LBA is identified; (b) a second LBA that is considered free is identified; (c) the second LBA is replaced with the first LBA; (d) the input buffer is written to a location, in the application data, that the second LBA references; and (e) the second LBA is added in the entry.Type: ApplicationFiled: October 14, 2022Publication date: April 18, 2024Inventors: Ranjit Mario Noronha, Sumanta Chatterjee, Margaret M.

Patent number: 10182945Abstract: Disclosed are hybrid wound dressings that include at least one front layer of a hydrophilic absorbent material and at least one layer behind the front layer that is made of an open-celled polymeric foam made from high internal phase emulsions (HIPEs). The hydrophilic absorbent material may be a natural polymeric material; a synthetic, non-foam polymer; or a material like glass microfiber. Each layer has a rate of fluid absorption and a capillary suction pressure (CSP) for a working fluid like blood plasma. The CSP increases from the front layer toward the layers behind the front layer, such that fluid is drawn away from a wound.Type: GrantFiled: May 22, 2018Date of Patent: January 22, 2019Assignee: Dristi, LLCInventor: Ranjit Chatterjee

Patent number: 10004646Abstract: Disclosed are methods for using open-celled polymeric foam wound dressings made from high internal phase emulsions (HIPEs). The wound dressings have a high capillary pressure and may reduce or obviate the need for treatments like negative pressure wound treatment (NPWT). Also disclosed are structures for HIPE foam wound dressings. The HIPE foam wound dressings typically include at least two layers of HIPE foam with different, but homogeneous, average cell sizes. The average cell sizes form a cell size gradient, with cell size typically decreasing from the front or face layer of foam toward the back layer of foam. The back layer of foam may be a collapsed layer, while the front layer or layers may be expanded. Compared with HIPE foams for other absorbent applications, the wound dressing foams may be higher in hydratable salts and higher in initial moisture levels.Type: GrantFiled: August 19, 2014Date of Patent: June 26, 2018Assignee: Dristi, LLCInventor: Ranjit Chatterjee

Publication number: 20020150540Abstract: Allergen neutralization compositions for use on inanimate objects having an effective amount of an allergy neutralizing aluminum ion, and a solvent. The allergen neutralization compositions are sprayable, and at least about 60%, by weight of the aluminum ion is provided as a salt of an anion selected from the group consisting of sulfate, chloride, nitrite, potassium sulfate and mixtures thereof. The composition preferably contains essentially no aluminum chlorohydarate, and may contain additional allergen denaturing compounds such as polyphenol compounds, hydrogen peroxide, salicylic acid, citric acid, lactic acid, glycolic acid, additional metal ions and mixtures of these. Other optional ingredients include film forming polymers to control the allergen containing dust. These allergen neutralization compositions provide excellent efficacy against various allergens, and specifically, the allergens associated with house dust mites and other common allergens such as cat dander, pollen and the like.Type: ApplicationFiled: February 8, 2002Publication date: October 17, 2002Inventors: Akikazu Yoshikawa, Ranjit Chatterjee, Ryoko Kobayashi
