Abstract: The present invention relates to a medicament delivery device comprising a housing, a compartment inside said housing for positioning a medicament container, an injection needle arranged to said housing, being connectable to said medicament container for delivering a dose of medicament, a manually operated activation mechanism for activating said device, an actuation mechanism operably connected to said activation mechanism and arranged to, upon activation of said activation mechanism, extend said injection needle from a first position inside said housing to a second position wherein a penetration of a patient is performed, a plunger rod arranged in said housing capable of acting on said medicament container for delivering a dose of medicament through said injection needle, a driver capable of acting on said plunger rod for delivering a dose of medicament.

Abstract: Certain aspects are directed to a portable and compact card holding and playing system comprising a card caddy with a detachable rotating mechanism, a flexible retaining device with at least one weighted element, a plurality of retaining discs, and a game plate using a number of flexible retaining mechanisms. The game plate is single and/or trifold with the trifold plate comprising a ferrous core with top and bottom laminate materials connected via hinges. The retaining disc is stackable, which can be placed on a number of cards or on each other. The card tray is preferably detachable from a base with a center divider that includes a magnetic component used to securely attach the card tray to the magnets embedded in the flexible retaining device and the base, thus allowing the kit to operate via magnetic and gravitational forces and be used in the presence of wind, turbulence or on uneven playing surfaces.

Abstract: A pipette tip made of plastic with an elongated tubular body with a lower opening at the lower end for the passage of liquid and an upper opening at the upper end for clamping onto an attachment of a pipetting device, wherein a seating region for the attachment is present next to the upper opening on the inner circumference of the tubular body, wherein at least one flattened area extending in the axial direction is present next to the upper opening on the outer circumference of the tubular body, the wall thickness of the tubular body gradually decreases in a cross-section through the tubular body, starting from one of the two regions of the tubular body adjoining the flattened area, in the flattened area towards its central region, and the flattened area has in the cross-section through the tubular body a straight or a less strongly curved profile than the adjoining regions.

Abstract: A computer-implemented method for teaching math is disclosed. The method comprises generating a number; generating movable items corresponding to the number defining a number of place values for representing the number; graphically marking place value areas corresponding to the place values; allowing a user to move the movable items into the place value areas to represent the number in terms of its place values.

Abstract: A computer-implemented method for teaching math is disclosed. The method comprises generating a problem for a user to solve; generating a graphical representation of a number associated with the problem; wherein the graphical representation is selected to facilitate subitizing of the number; and overlaying visual guidance on the graphical representation to guide a user as a means to drawing attention to a learning strategy for solving the problem; receiving and checking a user's input as a solution to the problem; and indicating to the user a correctness of the solution.

Abstract: A computer-implemented method for teaching math is disclosed. The method comprises displaying a challenge for a learner to solve; displaying in first area a plurality of moveable pieces; displaying a second area defining a receptacle to which the learner can move the moveable pieces in attempting to solve the challenge; and evaluating the learner's response to the challenge.

Abstract: A computer-implemented method for teaching math is disclosed. The method comprises displaying a number line graphic to indicate a relative order between numbers; generating a first problem comprising numbers at least some of which are indicated on the number line graphic; selectively providing guidance for solving the problem; and receiving a user's input as a solution to the first problem.

Abstract: Embodiments of the invention disclose a virtual manipulative to facilitate math learning. The virtual manipulative comprises a user interface to progressively form one on more columns to hold partial sums or number decompositions to assist a learner in computing a sum.
