US Patent:

42185351, Aug 19, 1980

Filed:

Dec 7, 1978

Appl. No.:

5/967324

Inventors:

Robert A. Ray - Fullerton CA

Assignee:

Beckman Instruments, Inc. - Fullerton CA

International Classification:

G01N 3114
C07G 702

US Classification:

435 12

Abstract:

An enzymatic reagent is provided for use in the kinetic measurement of the concentration of an enzyme substrate present in a sample and possessing the Michaelis-Menten relationship between reaction rate and substrate concentration. The reagent includes an enzyme such as glucose oxidase, uricase or urease for reacting with corresponding enzyme substrates such as glucose, uric acid or urea. In addition, the reagent includes a nonreacting competitive inhibitor of the enzyme. The inhibitor is present in an amount sufficient to improve the linearity of the reaction rate-concentration relationship associated with the enzyme substrate reaction at concentrations which are low relative to the Michaelis-Menten constant, Km, for the particular enzyme substrate reaction. The improved linearity, in turn, improves the accuracy of the kinetic measurements of substrate concentration made by linear output analyzers especially in an upper portion of the predetermined range where the relationship is particularly nonlinear.

Assignee:

Beckman Instruments, Inc. - Fullerton CA

International Classification:

G01N 3316
G01N 114

US Classification:

23259

Abstract:

Apparatus for the analysis of samples such as blood or urine includes a reaction cell for reacting the sample with a chemical reagent at a predetermined temperature. A heat exchanger is provided on the reaction cell for establishing the temperature of the cell. Reagent is pumped into the cell through a conduit, and a portion of the conduit is wound around the reaction cell in contact with the heat exchanger to preheat reagent in the conduit before the reagent is pumped into the cell.

Abstract:

One variation of a method—for controlling a breathing mask comprising a flow control module configured to mate to nostrils of a user and comprising an actuator configured to adjust obstruction to airflow out of the flow control module—includes: accessing a wake alarm time; accessing a sleep delay duration; at a first time, receiving an indicator that the user is preparing for sleep; in response to receiving the indicator, triggering the actuator to transition from a minimum-restriction position toward a maximum-restriction position at a second time succeeding the first time by the sleep delay duration, the actuator minimally obstructing airflow out of outlet port in the minimum-restriction position and maximally obstructing airflow out of outlet port in the maximally—restriction position; and, prior to the wake alarm time, triggering the actuator to transition back to the minimum-restriction position.

Abstract:

One variation of a dynamic tactile interface includes a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region; a substrate coupled to the peripheral region, a fluid conduit adjacent the deformable region, a fluid channel fluidly coupled to the fluid conduit, and a via fluidly coupled to the fluid channel and passing through the back surface; a bladder fluidly coupled to the via and the substrate; a structure adjacent a first side of the bladder; and a platen adjacent a second side of the bladder opposite the first side and compressing the bladder against the structure substantially perpendicular the longitudinal axis of the bladder and substantially parallel the substrate to displace fluid from the bladder and into the fluid channel to transition the deformable region from a retracted setting into an expanded setting.

Abstract:

A dynamic tactile interface includes a dynamic tactile layer and a manual fluid actuator. The manual fluid actuator includes a displacement device including a bladder, a platen adjacent the bladder, an elongated member coupled to the platen, and a rotary actuator, the elongated member and the rotary actuator translating rotation of the rotary actuator into translation of the platen, the platen compressing the bladder in response to rotation of the rotary actuator in a first direction and expanding the bladder in response to rotation of the rotary actuator in a second direction opposite the first direction.
