摘要:
An electrical and mechanical connection between a head worn communication device and an accessory thereto wherein mechanical connection means and electrical connection points at the communication device are placed at one and the same surface part, and further connection means and electrical connection points at the accessory are placed at one and the same surface part, such that a sliding action between the two surface parts will cause the respective mechanical connection means to grip each other while the respective electrical connection points gain contact with each other.

The invention concerns a hearing aid, which has a casing accommodating one or more sound to electric signal converting transducers (11,12) and a signal path from the transducer (11,12) to a receiver which provides a sound signal at the ear of the user. The signal processing is provided in the signal path to ensure a signal amplification/attenuation according to the needs of the user. A battery (6) is accommodated in the casing and a battery lid is arranged with a first side (1) facing the surrounding and a second side (2) facing the interior of the casing whereby the battery lid is operable for replacement of the battery. According to the invention the battery lid has means (3) for receiving at least one sound to electric signal converting transducer (11,12) and a sound transmission path is provided between the first side (1) of the battery lid and the at least one transducer (11,12).
摘要:
A mixing system (1) adapted to allow first contents of a first container (2) and second contents of a second container (3) to mix to form a material. The mixed material is retrieved to a syringe (20) without being foamed. The mixing system (1) comprises a transfer unit (5) which is adapted to receive the first container (2) at a first port (11), the second container (3) at a second port (12) and the syringe (20) at a third port (13). The transfer unit (5) further houses a number of fluid pathways (14, 15, 16) interconnecting the three ports (11, 12, 13) as well as a number of flow control members (17, 18, 19, 22) for controlling fluid flow between the containers (2, 3) and the syringe (20). At least one of the flow control members (17, 18, 19, 22) allows a user to switch between two states of fluid flow, one in which fluid flow is enabled between the first port (11) and the third port (13) as well as between the third port (13) and the second port (12), and one in which fluid flow is enabled between the second port (12) and the third port (13). The invention also relates to a transfer unit comprising first and second ports for receiving first and second containers, respectively, a third port for coupling to a syringe, a number of fluid pathways interconnecting the ports, at least one flow control member which allows a user to switch between two states of fluid flow, and a locking means to ensure that the at least one flow control member can only be manipulated when a syringe is coupled to the third port.
