A keyboard-operated tone-producing apparatus having, in combination, keyboard means the keys of which are mounted for downward depression to effect tone production in the apparatus and for longitudinal sliding to alter or bend the tone; electronic digital signal processor means; tone-generating means; pressure sensing means responsive to key depression to produce signals corresponding thereto for application to the signal processor means to produce corresponding digital signals applied to generate tones from the tone-generating means; means for causing the pressure sensing means to provide the same signal reference, upon key depression, irrespective of the point of pressure along the path of longitudinal sliding of the key; and means controlled in response to the last-named means and cooperative with the signal processor means as it controls the tone-generating means to produce one or all of variable range bending of the tone, center compensation for differing player techniques of key depression, and second striking of the key while depressed for second tone generation.

A locker includes a pair of upstanding sidewalls and at least one compartment defined between the upstanding sidewalls. A drying compartment includes upper and lower horizontal panels, at least one of the upper and lower panels being hollow and extending at least partially between the sidewalls. A pair of compartment sidewalls are connected to the panels, at least one of the compartment sidewalls being in fluid communication with the at least one hollow upper and lower panels. A perforated rear panel is connected to the compartment sidewalls and the upper and lower panels and is in fluid communication with an interior of the drying compartment. A fan is disposed in one of the compartment sidewalls. The fan draws air from at least one hollow upper and lower panels, directs it into the interior of the drying compartment, and the air is exhausted from the compartment though the perforated rear panel.

Interference in an electronic article surveillance (EAS) system is reduced by transmitting warning pulse at a predetermined time following the EAS marker exciter pulse. The predetermined time and duration of the warning pulse are chosen so that the warning pulse acts upon a noise interference avoidance process in a second non-cooperative EAS unit. More particularly, the warning electromagnetic pulse causes a timing change in a second synchronized electromagnetic exciter pulse produced by the second EAS unit when the second synchronized electromagnetic exciter pulse is concurrent with the first receive interval. This timing change causes the second EAS unit to no longer interfere with the first EAS unit.

The present invention provides a linear accelerator in which a rotatable conductive vane is employed to vary the electromagnetic coupling between adjacent accelerating cells. The vane is sealed off from the rest of the linear accelerator by an insulating partition, so the pressure around the vane can be higher than in the rest of the accelerator. This greatly simplifies the mechanisms which may be used to control the rotation of the vane, allowing a higher bakeout temperature in manufacture and a higher rate of rotation in use.

Flat panel images obtained during concurrent radiotherapy typically suffer from artefacts that relate to the pulses of MV energy. For a radiotherapeutic apparatus comprising a pulsed source of therapeutic radiation, a detector comprising control circuitry, an array of pixel elements, each having a signal output and an ‘enable’ input and being arranged to release a signal via the signal output upon being triggered by the enable input, and an interpreter arranged to receive the signal outputs of the pixel elements, the interpreter having a reset control, there are advantages in the control circuitry being adapted to reset the interpreter after a pulse of therapeutic radiation, prior to enabling at least one pixel of the array. Alternatively, the control circuitry can prompt a plurality of pulses by the pulsed source and then enable a plurality of pixels of the array. In effect, the therapeutic pulses are grouped into a short flurry of pulses. It is therefore preferred that the plurality of pixels comprises substantially all the pixels of the array.

A medical device package for receiving, and securely and removably retaining, a medical device includes main and minor cap members. The main cap member has a proximal end, a distal end and a cavity with a cavity opening at the proximal end. The cavity is configured to receive, and to securely and removably retain, the medical device at least partially therein. The minor cap member is configured to seal the cavity opening once the medical device has been received in the cavity. Kits further include a connector adapted for engaging the medical device member and breaching the minor cap member. A method for extracting a medical device from a medical device package includes first providing a medical device package as described above, with a medical device therein, and a connector. The method also includes breaching the minor cap member with the connector such that at least a portion of the connector enters the cavity of the medical device package. Next, the medical device is engaged by the connector and extracted from the medical device package.

A lancing device includes a lancing mechanism, a floating probe and a pressure tip. The lancing mechanism includes a lancet carriage, a lancet holder slidably connected to the lancet carriage, and a lancet attached to the lancet holder. The pressure tip of the lancing device is configured for engaging a target site and creating a target site bulge. The floating probe is adapted to floatably contact the target site bulge and to operatively interact with the lance carriage to control a penetration depth of the lancet into the target site bulge. A method for lancing a target site includes providing the lancing device describe above and contacting the pressure tip of the lancing device with the target site. The pressure tip is then urged towards the target site to create a target site bulge with the floating probe of the lancing device floating on a surface of the target site bulge. Next, the target site bulge is lanced while the floating probe operatively interacts with the lance carriage to control a penetration depth of the lancet.
