US Patent:

20010032878, Oct 25, 2001

Filed:

Feb 9, 2001

Appl. No.:

09/780029

Inventors:

Yiannis Tsiounis - New York NY, US
Charles Doherty - Freeport NY, US
Benjamin Reddy - New York NY, US
Eilliott Richelson - New York NY, US

International Classification:

G06F017/60

US Classification:

235/379000

Abstract:

Methods and systems consistent with the present invention provide a simple and easy-to-use system to make electronic payments on the Web. Specifically, methods and systems consistent with the present invention provide anonymity, security and accountability. To do so, pre-paid stored value card (“cash card”) including a card identification number for a predetermined amount of money may be purchased at a point of sale. To ensure security, Personal Security Codes are established for a user at a server. To use the cash cards, a user may visit a Web merchant, select an item to purchase, and enter the card identification number and the Personal Security Code to transmit for confirmation to the server. The server subtracts the cost of the item from the predetermined amount on the cash card.

Appl. No.:

09/780031

Inventors:

Yiannis Tsiounis - New York NY, US
Charles Doherty - Freeport NY, US

International Classification:

G06F017/60
H04K001/00

US Classification:

705/071000, 705/077000, 705/078000, 705/072000

Abstract:

The present invention provides methods and systems for securing payment over a network from a customer to a merchant. A trusted party component receives an instruction from the customer to pay the merchant, the instruction including confidential payment information of the customer. The trusted party component creates payment authentication information based on the confidential payment information. Based on the payment authentication information, the trusted party component pays the merchant on behalf of the customer without the confidential payment information of the customer being disclosed to the merchant.

Filed:

May 16, 1984

Appl. No.:

6/610760

Inventors:

Charles F. Doherty - Quincy MA
Robert E. Johnson - Pembroke MA

Assignee:

Pyrotector, Inc. - Hingham MA

International Classification:

G01T 1185

US Classification:

250381

Abstract:

An ionization detector unit for use in a smoke detector includes a housing wall enclosing an ionization chamber, the wall having openings for passage of air through the chamber, the frontal surface of the wall that is exposed to an oncoming air flow from a given direction being inclined relative to an intersecting second surface exposed to the flow. The frontal surface is shaped and positioned to deflect the air flow generally toward the second surface, and the second surface is shaped and positioned to deflect the air flow generally toward the frontal surface, the shape and position of the surfaces cooperatively arranged to cause the deflected air flows to converge and form a region of air in the vicinity of the intersection of the surfaces that is at higher pressure and slower velocity than the oncoming air flow. Apertures are provided in the frontal surface of the housing to enable entry of air from the vicinity of the intersection to establish relatively slow, laminar air flow through the chamber, thereby to enable an effective ion current to be maintained within the chamber despite high velocity of oncoming air.

Abstract:

A radiation detector for use in hazardous locations, comprising an explosion proof housing with a viewing window and a detector element positioned inside the housing to receive radiation through the viewing window, and means within the housing to apply test radiation onto the external face of the viewing window directly. In one embodiment of the invention the viewing window is recessed in a housing cavity with a flared wall and the test radiation is applied from a housing portion that extends forwardly of the plane of the viewing window. In a preferred embodiment of the invention the housing is formed of front and rear portions which are rotatable in relation to each other, and the viewing window is mounted in a surface of the front portion which is inclined at a 45. degree. angle to the axis of rotation of the portions, and the rear portion has mounting means enabling mounting of the detector so that it can rotate about an axis disposed at a 45. degree. angle to the axis of rotation of the portions, thereby allowing adjustment of the detector to view in any desired direction.
