4. The control unit of claim 3 , wherein the housing includes a rigid portion located in a central portion of the housing distinct from each end portion of the housing, wherein the end portions of the housing are configured to bend approximately 15-60 degrees.
5. The control unit of 1 , wherein the housing includes at least one of a particulate substance and a ferrite substance.
6. The control unit of claim 5 , wherein the housing includes a ferrite substance, the ferrite substance reflecting a radiofrequency signal transmitted by an antenna contained within the housing.
7. The control unit of claim 1 , wherein the housing includes a ferrite substance, the ferrite substance absorbing a radiofrequency signal transmitted by an antenna contained within the housing.
8. The control unit of claim 1 , wherein the housing is at least three times as large in a lateral direction as in a height direction.
9. The control unit of claim 1 , wherein the pair of electrical contacts are disposed equidistant from a center of the housing.
10. A control unit, comprising:
a carrier configured to be attached to a subject, the carrier including:
a first planar surface;
a connector protruding from the first planar surface, and
a circular electrical contact portion formed on the first planar surface and surrounding the connector; and
a housing configured to contain at least one processing device and a circuit electrically coupled to the at least one processing device, for releasably connecting to the carrier via a mechanical connection in a center portion of the housing, the housing including:
a second planar surface facing the first planar surface of the carrier;
a recess disposed on the second planar surface and configured to receive the connector of the carrier; and
a pair of electrical contacts on the second planar surface of the housing distinct from the center portion, the pair of electrical contacts being separated from each other and electrically coupled to the circuit, and the pair of electrical contacts being disposed equidistant from a center of the recess at a distance equal to a radius of the circular electrical contact portion on the first planar surface of the carrier,
wherein, when the housing is connected to the carrier via the mechanical connection, both of the electrical contacts in the pair of electrical contacts electrically contact the circular electrical contact portion exposed on the first planar surface of the carrier.
11. The control unit of claim 10 , further comprising a primary antenna contained within the housing and configured to communicate with a secondary antenna associated with an implant unit configured for placement in a subject.
12. The control unit of claim 10 , wherein the housing is configured to include a flexible portion.
13. The control unit of claim 12 , wherein the center portion of the housing is rigid and distinct from each end portion of the housing, wherein the end portions of the housing are configured to bend approximately 15-60 degrees.
14. The control unit of 10 , wherein the housing includes at least one of a particulate substance and a ferrite substance.
15. The control unit of claim 14 , wherein the housing includes a ferrite substance, the ferrite substance reflecting a radiofrequency signal transmitted by an antenna contained within the housing.
16. The control unit of claim 10 , wherein the housing includes a ferrite substance, the ferrite substance absorbing a radiofrequency signal transmitted by an antenna contained within the housing.
17. The control unit of claim 10 , wherein the housing is at least three times as large in a lateral direction as in a height direction.
18. The control unit of claim 10 , wherein the pair of electrical contacts are disposed equidistant from a center of the housing.
19. A control unit for attachment to a subject, the control unit comprising:
a carrier configured to be attached to the subject, the carrier including:
a first planar surface;
a connector protruding from the first planar surface, and
a circular electrical contact portion formed on the first planar surface and surrounding the connector; and
a housing configured to contain at least one processing device and a circuit electrically coupled to the at least one processing device, for releasably connecting to the carrier via a mechanical connection, the housing including:
