Embodiments of the present invention can be directed to systems, apparatuses, and methods for performing transactions through mobile communication devices using telecommunications networks, systems, or proximity near-field communications systems. Embodiments may be directed to a mobile communication device displaying an application authentication element including a pre-selected authentication element. The application authentication element may include transaction data associated with a transaction conducted by a mobile communication device. The mobile communication device may obtain the pre-selected authentication element by either transmitting a request to a server computer or retrieving the pre-selected authentication element from a secure memory in the mobile communication device. A user authentication token may then be received by the mobile communication device from the user. The mobile communication device may then generate a secret token derived from the user authentication token, and if the secret token is correlated to a secret reference token, a transaction may be conducted.

A safety needle includes a needle with a sharp end and a needle shield. The needle shield includes collapsible interlocking members, wherein one member is an end member with a hole surrounding the needle, a spring inside the collapsible interlocking members that applies an expanding force on the collapsible interlocking members, a releasable latch structure that retains the collapsible interlocking members in a collapsed state, wherein when the releasable latch structure is actuated the collapsible interlocking members expand and enclose the sharp end of the needle, and a closing structure that prevents the sharp end of the needle from exiting the hole after the collapsible interlocking members enclose the sharp end of the needle.

A system and automated method for verification of employment history regarding a job applicant, the method including receiving information identifying an applicant, receiving employment history information for the job applicant, receiving information identifying an identified verification contact for verification of the employment history information, automatically providing the identified verification contact with a question pertaining to employment history information, receiving an answer from the identified verification contact, storing the answer.

The invention relates to an imprint apparatus for carrying out a two-step process for transferring a pattern from a template (1) to a target surface of a substrate. The apparatus works by creating an intermediate disc, e.g. from a flexible polymer stamp (10), by imprint from the template in a first imprint unit (200). A feeder device 410 is then operated to feed the intermediate stamp to a second imprint unit (300), where it is used to make an imprint in a target surface of a substrate.

A device and related method for the removal of subcutaneous adipose layers comprises a laser source; an optical fiber for conveying a laser beam emitted by the laser source; and a hollow cannula for guiding the fiber to the subcutaneous treatment area. The cannula has a curved portion at its distal end, where the curved portion can be shaped to roughly conform to the contour of the patient's body structure. In this way, laser energy from the fiber, applied to the adipose layers, is generally directed away from the lower dermis of the patient, minimizing the risk of non-reversible damage to the dermis, including skin necrosis. In another embodiment, the optical fiber is a side-firing fiber that directs the laser energy away from the dermis. In other embodiments, a radiation detector, such as a thermal or optical sensor, monitors the temperature at the surface of the skin above the treatment area to warn the operator of harmful temperatures in the lower dermis. In another embodiment, a temperature sensitive material is applied to the surface of the skin above the treatment area to warn of harmful dermal temperatures. In another embodiment, a cooling mechanism cools the surface of the skin above the treatment area to prevent damage to the dermis.

The present invention relates to methods and compositions for the cryopreservation of pluripotent cells in general and human embryonic stem (ES) cells in particular. The stem cells are grown on a bottom layer of solid support matrix and subsequently covered by a top layer of solid support matrix forming a matrix-cell-matrix composition, to which an effective amount of cryopreservation media is added, prior to freezing. The methods of the invention yield cryopreserved cells that exhibit an increase in cell viability and a decrease in cell differentiation, facilitating storage, shipping and handling of embryonic stem cell stocks and lines for research and therapeutics.

Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

Devices, systems and methods are disclosed which relate to optimizing a minimum cost function associated with buried asset lines by using a GIS application to generate a “dynamic buffer” around each asset line based on a risk management algorithm. A risk management algorithm, by which a GIS application can generate a “dynamic buffer”, is employed to minimize asset line damage risk and operating costs by balancing potential costs from damage against the fixed labor costs of manually screened and located tickets. Embodiments of the invention utilize the geography of the situation as well as factors for the asset itself.

Devices and methods are disclosed for protecting individuals from the sharp ends of medical objects following use on a patient. Such sharp objects include hypodermic needles, scalpel blades, cannulae, trocars, and the like. The invention utilizes a disposable protective cover for the used sharp. The protective cover is designed to surround and embed the sharp in a permanent cover that is blunt and will not permit further puncture or cutting with the sharp. In an embodiment, the protective cover also absorbs any fluids on or in the used sharp and prevents any fluids from escaping the protective cover. The sharp cover is configured to irreversibly lock, once closed. A refillable or replaceable dispenser dispenses the protective covers at points of use. A disposable receptacle receives the used sharp embedded in the protective cover. When the receptacle is full, the entire receptacle may be discarded in a medical waste container.

An ATM includes a user interface having plural electronic ink displays. Displays can be used as identification labels. A display identifying the function of a transaction function device can be located adjacent to that device. Displays can also be used to provide instructions to machine users. A display on how to insert a card into the ATM can be located adjacent the card input slot. An display can be in direct communication with both a card reader and an encryption pin pad (“EPP”). Upon suspecting card reader tampering, the card reader can instruct the display to present a message warning of the situation. Likewise, upon suspecting EPP tampering, the EPP can instruct the display to present a warning message. Displays can also instruct a machine user on when and when not to insert their PIN depending on the mode of the EPP.

An automated system (100) and method for optimizing project risk and return from the perspective of the sponsor. The project, project features and feature options are defined using project design system and project financial system data.
