Abstract: The present invention relates to a novel form of concrete formwork for reinforced concrete that relates generally to building construction, and particularly to an improvement to reinforced concrete with an automated self-installing concrete formwork where the system allows all elements required for the concrete pour to be pre-fabricated in a modular way to reduce human error on site and ease speed with which concrete can be being poured onto the rebar for curing.

Abstract: The present invention relates to a novel form of self-locking mechanical rebar coupler which is able to easily couple neighboring rebars by way of an inserting plug welded to one side of the rebar, which penetrates a receiving socket which is welded to another piece of rebar. It is then locked into place by a spring-loaded dowel which penetrates the inserting plug when the inserting plug pushes down a cap at the bottom of the receiving socket which had been holding the spring-loaded dowel in place. The purpose of this coupler is to transfer a load against tensile force and compression force in a stable manner by coupling two separate pieces of rebar and locking them into place. Various diameters of rebar can be used in this self-locking mechanical rebar coupler. The assembly by providing a self-locking rebar coupling, is aimed to reduce the size of rebar components which can be combined together on a construction site and improve construction speed.

Abstract: An enclosure or housing for an air monitoring instrument package for mounting on the roof or other surface on the outside of vehicles such as cars, trucks, buses, trams, trains and ships. By measuring air pollutants from moving vehicles, it is possible to explore the distribution of air pollutants throughout a city or rural area for the identification of sources of different pollutants, estimating human exposures to air pollutants, and mapping air pollutants with high resolution. The disclosed device provides continuous sampling of outside air while simultaneously protecting the delicate instruments from weather elements such as high wind, rain, snow, sleet and hail. The design also allows a nearly constant flow rate of sampled air independent of vehicle velocity. An optional impaction region further reduces transmission of mist and large particles to the chamber containing the measurement package.

Abstract: The techniques disclosed herein enable systems to safely deploy a plurality of upgrade variants to different resource units that provide a service by utilizing small-scale deployment and validation. To deploy upgrade variants, a system receives a selection of upgrade variants from a feature group and automatically selects an appropriate set of resource units at which to deploy the upgrade variants. The system is further configured to collect and analyze telemetry data from the set of resource units to determine if any problems have occurred as a result of the deployed upgrade variants. By analyzing the telemetry data, the system can also identify one or more upgrade variants that are causing the problems. In response, the system can remove the identified variants and proceed with deployment of the remaining upgrade variants.

Abstract: A drug delivery system comprises means to create a log of expelled dose amounts of drug. Stored dose amounts determined within a given time period are combined to a single combined dose amount. The given time period is initiated by a detected expelling event taking place (i) a given amount of time after a previous detected expelling event, or (ii) after a given detected action. By this arrangement it is possible to create a log corresponding to what a user considers to be a single dose, i.e. combining “split doses” to create a single log entry for a per se split dose.

Abstract: The present invention makes use of a modular Folded Tubular Photometer to measure the concentrations of gas-phase species and/or particles, including especially air pollutants such as ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2) and black carbon particulate matter, by means of absorbance of ultraviolet (UV), visible or infrared (IR) light. The optical bench makes use of modular components (tubes and mirror assemblies) that allow construction of path lengths of up to 2 meters or more while maintaining low detection cell volumes. The long path lengths, low cell volumes, and the innovation of pressure equalization during the absorbance measurements enable sensitive detection of ambient air pollutants down to low part-per-billion levels or less for gas species, and extinctions down to 1 Mm?1 or less for particulate matter, corresponding to ˜0.13 ?g/m3 or less for black carbon particulates.

The system further comprises processor means configured to determine (i) on the basis of measured values from the first sensor means, a rotational position of the clutch element, (ii) on the basis of measured values from the second sensor means, a high-speed condition in which the rotational speed of the clutch element exceeds a given threshold level, and (iii) indicate an error state if the high-speed condition is detected.

Abstract: Apparatuses and methods providing a ballast system for adjusting the center of gravity of a standardized front opening wafer container. Various embodiments of the disclosure present ballast systems that are low profile, do not require modifications to the shell of the wafer container, and can be retrofit to existing wafer carriers. In some embodiments, these capabilities are accomplished by a ballast that mounts to a kinematic coupling plate of the wafer container. In one embodiment, the ballasting can also provide sufficient counter force to the lifting forces associated with purging of the wafer container, thereby preventing “lift off” of the wafer container during purging operations. The ballasts can be removed for shipping of the wafer container, thereby decreasing shipping costs.

Abstract: A medial assembly comprises a logging first unit adapted to be mounted on a drug delivery device second unit from a fully un-mounted to a fully mounted position along a path. The first unit comprises a switch operatable between an off- and an on-state when the first unit is mounted on the second unit, the switch being in the on-state when the first unit is mounted within a first distance from the fully mounted position, and in the off-state when the first unit is mounted outside the first distance from the fully mounted position, and a snap lock operatable from an initial state through an expanded state to a snap-in state when the first unit is mounted on the second unit, the snap lock being in the snap-in state when the first unit is mounted within a second distance from the fully mounted position, the second distance being shorter than the first distance. By this arrangement it is ensured that the switch will be in the on-state before the snap lock is in the snap-in state.

Abstract: An add-on logging device (100, 300) mounted to a drug delivery device is turned on when the cap is removed. After a given amount of time in inactivity the sensor means of the add-on device is turned off automatically to save energy. If the user takes a dose of drug this is not detected as the add-on device is only turned on when the cap is removed. According to the present invention a warning message is provided when the cap is re-mounted after the sensor means has been turned off automatically, the warning message indicating to a user that an expelled dose may not have been detected.
