摘要:
Robotic hands (10) and finger modules (12-1, 12-2, 12-3, 12-4) include an underactuated finger with multiple joints (18) including a distal joint (18-3), an intermediate joint (18-2), and a proximal joint (18-1). A brake subsystem (158) in communication with each of the joints selectively locks and unlocks the joints individually. A robotic hand can selectively lock the joints of a finger individually such that one or more joints are locked while one or more joints are unlocked. In addition, the finger module can drive a tendon (130) coupled to the joints to flex the underactuated finger in a manner determined by which of the joints is locked and which of the joints is unlocked. A robotic hand can move an underactuated finger with its distal and proximal joints unlocked until the finger makes contact with an object, and lock the proximal joint, in response to contact made with the object, while the distal joint remains unlocked.

A vehicle includes a main body, a transmission having a plurality of gear stages, a data storage, and an electronic controller. The data storage stores a vehicle running condition data that includes at least one of a prescribed vehicle running condition, a sensed vehicle running condition and a transmitted vehicle running condition. The electronic controller determines a gear shift of the gear stages of the transmission based on future vehicle speed that has been estimated based on the vehicle running condition data.

A method of pupil segmentation in a digital image of a vertebrate eye, said image being an intensity image composed of pixels having each a specific intensity value, the method comprising the steps of: deriving a texture image from the intensity image, said texture image being composed of pixels having each a specific contrast value; forming a combined image by point-wise combining the intensity image with the texture image, identifying a set of pixels in the combined image which fulfill a combined low-intensity and low-contrast criterion; and approximating a boundary of said set by a convex curve and taking said convex curve as a boundary of the pupil.

A phased array antenna system has at least one trough reflector, each trough reflector having at least one phased array located at a feed point of the reflector, and an array of elements located near to a point equal to one half of a center transmission wavelength. A method of decoding a receive signal includes propagating a transmit signal through a transmit and a receive path of a phased array to generate a coupled signal, digitizing the coupled signal, storing the digitized coupled signal, receiving a signal from a target, and using the digitized coupled signal to decode the signal from the target. A method of modeling the ionosphere includes transmitting measuring pulses from an incoherent scattering radar transmitter, receiving incoherent scatter from the transmitting, and analyzing the incoherent scatter to determine pulse and amplitude of the incoherent scatter to profile electron number density of the ionosphere.

The technical field of the invention is CO2 capture and sequestration, as well as gas separation and purification technologies. In an aspect is a process for capturing purified CO2 from a CO2-containing gas, comprising steps: (a) contacting in an absorber column the CO2-containing gas with an absorption solution comprising water, ammonia, and potassium carbonate, to enable adsorption of CO2, thereby producing a CO2-depleted gas and a CO2-rich solution; and (b) subjecting the CO2-rich solution to desorption conditions in a regeneration column producing a purified CO2 gas stream and a CO2-depleted solution.

An electroadhesive gripping system includes a vacuum- augmented gripper. The gripper can include an electroadhesive surface associated with one or more electrodes and a load-bearing backing structure coupled to the electroadhesive surface. The backing couples to the backside of the electroadhesive surface so as to at least partially define a shape of the electroadhesive surface. The backing is configured to flex between a curled shape and an uncurled shape. A spreading arm is configured to apply force to the backing so as to flex the backing from the curled shape to the uncurled shape. When positioned next to a substrate, the uncurling motion of the backing can cause the electroadhesive surface to become vacuum sealed to the substrate. A power supply can be configured to apply voltage to the electroadhesive surface.

A method of building structures using diamagnetically levitated manipulators includes depositing, with a first end effector attached to a first manipulator, a first adhesive at a first location on a first surface, picking up, with a second end effector, an article, moving the article to the surface, and placing the article on the adhesive on the surface.

The present invention pertains to a method of generating a normalized digital image of an iris of an eye for the purpose of creating an iris code for identification of vertebrates, including humans, the method comprising the steps of: capturing one or more digital images of the eye with a camera; constructing a plurality of imaginary outer iris boundaries in the one or more digital images, based on a known dimension of the outer iris boundary of the eye of a given species of vertebrates; and using said imaginary boundaries for transforming the one or more digital images into a plurality of normalized iris image that are insensitive to variations in a dimension of a pupil of the eye.
