摘要:
The invention provides, in some aspects, devices for image acquisition that use seals (e.g., O-rings) between concentrically disposed portions of an enclosure and an optics assembly (or sub-assemblies thereof) in order to protect image acquisition components from the surrounding environment (and vice versa) while, at the same time, providing adequate friction for both adjusting and locking focus. Such devices include, in one aspect of the invention, an image capture medium (e.g., a CMOS sensor, CCD array, etc.) that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure, rotatably. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal (e.g., an “O-ring”) is disposed between, and in contact with, the optics assembly and the enclosure, e.g., along these corresponding lengths. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing (or reducing a risk of) contamination from the environment (e.g., water, chemicals, dirt, dust, etc.) from entering into the enclosure and vice versa.

A machine vision image acquisition system is provided with a housing or enclosure that protects the acquisition system components from an industrial environment. The machine vision image acquisition system has a focusing mechanism that can be actuated externally to the housing. The focusing mechanism uses a gear drive to transmit externally actuated focus adjustments to the optical components of the acquisition system.

A system and method for facilitating a financial transaction over a network including use of a passphrase account identifier is described herein. In one embodiment, a system for facilitating a financial transaction over a network comprises a communication interface; and a payment provider system configured to receive via the communication interface a passphrase account identifier from a merchant system, match the passphrase account identifier to a corresponding funding instrument number of a corresponding funding instrument, communicated the corresponding funding instrument number to an issuer system, receive from the issuer system a notification indication of one of acceptance of the funding instrument or decline of the funding instrument, and communicate back to the merchant system the notification indication.
摘要:
A method and a system conducts payment transactions via instant messaging. The system includes a messaging interface to receive a payment transaction request at a payment application from a network-based device via a network. The messaging interface facilitates substantially instant communication over the network. The payment application, responsive to receiving the payment transaction request, transfers a payment from a user associated with the network-based device to a third party.

Disclosed are methods and apparatus for automatic visual detection of events, for recording images of those events and retrieving them for display and human or automated analysis, and for sending synchronized signals to external equipment when events are detected. An event corresponds to a specific condition, among some time-varying conditions within the field of view of an imaging device, that can be detected by visual means based on capturing and analyzing digital images of a two-dimensional field of view in which the event may occur. Events may correspond to rare, short duration mechanical failures for which obtaining images for analysis is desirable. Events are detected by considering evidence obtained from an analysis of multiple images of the field of view, during which time moving mechanical components can be seen from multiple viewing perspectives.

A payment system includes a transaction identification system to identify a plurality of purchase transactions, established utilizing one or more transaction systems that impose a plurality of corresponding payment obligations on a particular user. An interface generator generates an aggregation interface that presents the plurality of purchase transactions to the first user. The plurality of purchase transactions are presented in conjunction with a payment option to initiate an automatic payment process with respect to at least a subset of the purchase transactions. A payment engine initiates the automatic payment process with respect to the first subset of plurality of purchase transactions upon election by the first user of the payment option.

A headrest assembly (36) for a vehicle seat (10) and a method of installation. The headrest assembly (36) includes a support post (28) pivotally connected to an installation post (16) via an installation hinge (30). The installation post (16) is installed into a guide sleeve (14) of the seat back (12) such that the installation hinge (30) is still exposed, allowing the headrest body (34) to tip down and forward. The seat (10) is then installed into the vehicle body (50), after which, the headrest body (34) is tipped up and pushed down until a support post notch (38) engages with an installation catch (20) mounted on the guide sleeve (14). The headrest (36) will now remain in its use position with the hinge (30) contained within the guide sleeve (14).
