Title: Biometric solution enabling high throughput fare payments and system access
Inventor: SYED SALMAN H
IPC: G06Q20/40
Filed: 2015-02-12
Granted: 2020-03-10
Abstract: A communications network places in data communication an access point controlling access to a controlled access area; a server; and a medium-long range wireless communications transceiver. The transceiver detects presence of a portable electronic device outside the access point. The server obtains an indication that a user of the portable electronic device has been authenticated to the portable electronic device and initiates a payment approval process which is completed before the user seeks to pass through the access point. Based at least in part on the authentication and success of the payment approval process, the server provides to the access point an electronic token indicating that the user, bearing the portable electronic device, is to be allowed to pass through the access point into the controlled access area.

Title: Preparation of titanium catecholate complexes in aqueous solution using titanium tetrachloride or titanium oxychloride
Inventor: KING EVAN R
IPC: C07C37/66
Filed: 2016-03-16
Granted: 2023-09-05
Abstract: Titanium coordination complexes, particularly titanium catecholate complexes, can be attractive active materials for use in flow batteries. However, such coordination complexes can be difficult to prepare from inexpensive starting materials, particularly in aqueous solutions. Titanium oxychloride and titanium tetrachloride represent relatively inexpensive titanium sources that can be used for preparing such coordination complexes. Methods for preparing titanium catecholate complexes can include combining one or more catecholate ligands and titanium oxychloride in an aqueous solution, and reacting the one or more catecholate ligands with the titanium oxychloride in the aqueous solution to form the titanium catecholate complex. Titanium tetrachloride can be used as a precursor for forming the titanium oxychloride in situ. In some instances, the titanium catecholate complex can be isolated in a solid form, which can be substantially free of alkali metal ions.

Granted: 2020-07-21
Abstract: An aircraft rotor assembly includes a central hub, and rotor blades coupled to the hub for rotation with the hub about an axis. Each blade has a Lock number of approximately 5 or greater. A  discrete hinge for each blade allows for out-of-plane motion. A lead-lag pivot for each blade formed by a flexure couples the associated blade to the hub. Each pivot is a radial distance from the axis and allows for in-plane lead-lag motion of the associated blade relative to the hub. Each pivot allows for in-plane motion from a neutral position of at least 1 degree in each of the lead and lag directions. Elastic deformation of the flexure produces a biasing force for biasing the associated blade toward the neutral position. The biasing force is selected to achieve a first in-plane frequency of greater than 1/rev for each blade.
