The invention relates to a stick / pole grip (1), particularly for walking sticks, trekking poles, alpine ski poles, cross-country ski poles and Nordic walking poles, with a grip body (3) and with a device (11-14) for adjustably fastening a hand-retaining device, particularly provided in the form of a hand strap (2) or a glove. The inventive stick / pole grip is characterized in that the hand-retaining device has, at least in a fastening area, a fastening means provided in the form of a strip, a strap, a belt or a rope for fastening to the stick / pole grip (1), and that the device has an eccentric element (11) that can rotate and / or pivot about an axis (12), this eccentric element (11) having a surface in the fastening area whose radius (a, b, c) increases toward the axis (12) in a fixing direction of rotation (F) at least in a step-by-step, continuously, ribbed or stepped manner so that the fastening means guided in the fastening area between this surface of the eccentric element (11) and a fixed abutment (14) is clamped between the eccentric element (11) and the abutment (14) by rotating or pivoting the eccentric element (11) in the fixing direction of rotation (F). This design makes possible an extremely simple and reliable variable fastening of a hand-retaining device on the stick / pole grip.

An adjustable and foldable V-shaped hay rake is an agricultural tool used for raking hay on fields, in which, for each arm of the hay rake, all the mechanisms for moving the arm are centered on a single adjustable master support plate.

Capacitive touch screen including first and second substrates (2, 4) that extend parallel to and at a distance from each other, said first and second substrates (2, 4) being made of a transparent, dielectric material, a first series of electrodes (6), made of a transparent, electrically conductive material, being arranged on at least the surface (2a) of the first substrate (2) that faces the second substrate (4), said touch screen being characterized in that it includes means for keeping the space between the two substrates (2, 4) constant.

A coupling for connecting ground engaging tools to a lip of an excavator bucket or similar uses an eccentric rotating lock, whereby rotation of the lock alters the distance between bearing surfaces and thus allows tightening of the lock.

A gripping assembly with gripping members, as part of a grapple attachment, used to grasp and manipulate elongated objects, for example pipe, is described. Due to the gripping action of the gripping members and tilt control capabilities of the grapple attachment, total positive control of the pipe is maintained, even if the gripping assembly picks up pipe off center. The grapple attachment is able to be used on all pipe surface types, including pipe surfaces that are dirty, snow or ice covered. The gripping members are configured to prevent damage to the pipe and to adjacent pipes, and will not crush the pipe.

The invention relates to a new method for measuring cytotoxic activity of immune cells, and to methods and products for treating abnormal immune responses.

An upright wheelchair with a chassis (29, 22), a seat (2) arranged pivotably on the chassis (29, 22), which can be pivoted from a substantially horizontal seating position to a substantially vertical standing position during upright motion, and at least one footrest (16) arranged on the chassis (29, 22), which is lowered to the ground in the standing position, is characterised in that when the seat (2) is in the seating position the footrest (16) is inclined at an angle (α) relative to the horizontal (H) and the angle (α) returns to zero during upright motion.

An ophthalmic instrument for use with a subject's eye, comprising an interferometer having a test arm in which the subject's eye is to be positioned and a reference arm, the reference arm including a mirror adapted to be positioned such that the reference arm has a predetermined length, and an ophthalmic apparatus coupled to the interferometer such that, by altering a test arm length, a length between the ophthalmic apparatus and the eye is also altered. The mirror is positioned to achieve the predetermined length and a length of the test arm is adjusted such that interference between the light reflected from the eye and the light reflected from the mirror is achieved, the ophthalmic apparatus is optically aligned with the eye.

Methods and devices are provided for adjusting the height of devices in a gastric restriction system. In general, the methods and devices allow one or more implantable housings coupled to an implantable restriction device to have an adjustable height. The housing can include, for example, a fill port housing, a sensor housing, and any other type of housing that can be used in an implantable restriction system and desired to have an adjustable height. The housing can lower in profile over time, e.g., as the patient loses weight, thereby maintaining the housing in a generally predictable location where it can be found and accessed.
