Title: Formulations and methods for solid chitosan-containing blends
Inventor: NICHOLS EVERETT J
IPC: C08J3/05
Filed: 2010-06-18
Abstract: Chitosan-containing blends and methods of dissolving and using chitosan are disclosed. A blend includes a solid acid or a solid agent that generates a proton in situ in the presence of water mixed together with a dry solid chitosan, and may optionally contain other components. The blends are in a dry, free-flowing, particulate form. Methods of dissolving a blend typically comprise adding a quantity of the blend to a low volume of water and mixing until the chitosan and solid acid or solid agent are dissolved and then further diluting this mixture by the addition of water, or used as-is. Devices containing the blends are also described along with methods of using the devices, such as for controlled release of solubilized chitosan in a body of water, such as a stream, containing impurities (e.g., particles, sediment, or suspended matter or dissolved substances) to cause flocculation or precipitation of such impurities.

Title: Dynamic autofocus operations
Inventor: BRUNNER RALPH
IPC: G03B13/36
Filed: 2012-09-14
Abstract: Systems, methods, and computer readable media for dynamically adjusting an image capture device's autofocus (AF) operation based, at least in part, on the device's orientation are described.

Title: Embolic coil detachment mechanism with heating element and kicker
Inventor: LORENZO JUAN A
IPC: A61F2/95
Filed: 2013-03-22
Abstract: Provided herein are a system, method, and apparatus for delivering a therapeutic device, e.g. an embolic coil, from a delivery tube at a target site in a patient's body. A heating element is disposed in the delivery tube that can be actuated remotely, and a layer of low temperature adhesive is applied at the heating element to retain the therapeutic device.  The kicker in the form of, for example, a compressed spring is mounted within the delivery tube so as to be in contact with the therapeutic device for applying a constant ejector force that is countered by the adhesive force of the low temperature adhesive. When the heating element is actuated, the spring's ejector force overcomes the softened adhesive's adhesive force to force the therapeutic device out of the delivery tube.
