An implantable medical device includes a structural body made from a superelastic material and includes one or more marker holders integrally formed on the structural body. Each marker holder is designed to hold a radiopaque marker which has a level of radiopacity greater than the superelastic material. The radiopaque marker can be made from a nickel-titanium alloy which includes a ternary element. The ternary element can be selected from the group of elements consisting of iridium, platinum, gold, rhenium, tungsten, palladium, rhodium, tantalum, silver, ruthenium, and hafnium. In one form, the marker holder includes a pair of projecting fingers connected together at a notched region to cooperatively create a particular-shaped opening. This opening, in turn, is adapted to receive a similarly shaped portion formed on the radiopaque marker. In one form, the radiopaque marker includes an inner core which is partially, or completely, encased by an outer layer. This inner core can be made from a highly radiopaque material while the outer layer is formed from a material that is easier to weld to the marker.

A wireless combination time, frequency and spectral shaping communications method that transmits data in convolution unit matrices (data frames) of N×N (N²), where generally either all N² data symbols are received over N spreading time intervals (each composed of N time slices), or none are. To transmit, the N² sized data frame matrix is multiplied by a first N×N time-frequency shifting matrix, permuted, and then multiplied by a second N×N spectral shaping matrix, thereby mixing each data symbol across the entire resulting N×N matrix (TFSSS data matrix). Columns from this N² TFSSS data matrix are selected, modulated, and transmitted, on a one element per time slice basis. At the receiver, the replica TFSSS matrix is reconstructed and deconvoluted, revealing the data. The method can accommodate multiple users at once, can adapt to changing channel conditions, and is particularly useful for coping with channel impairments such as Doppler shifts.

A digital nonlinear adaptive mechanism for frequency offset compensation for use in a digital Frequency Shift Keying (FSK) receiver such as a Bluetooth GFSK receiver. The mechanism is intended to aid in the recovery of a frequency-modulated signal in the presence of an unknown additive frequency offset, which could be greater than the peak frequency deviation and which must be suppressed to enable proper data recovery in the receiver. The mechanism utilizes a demodulator to convert the frequency offset into a digitally represented DC level. This level is extracted by a non-linear estimator based on peak detectors and filters. Active suppression of the DC level is achieved by feed-forwarding the estimated value into a subtractor that removes it from the digital signal. A gear shift mechanism incorporated within the DC estimation block enables the dynamic control of the DC estimation process. Charge and discharge coefficients are configured dynamically to provide fast frequency offset compensation during the reception of the redundant header at the beginning of a packet and relatively slow frequency offset compensation during the subsequent reception of the payload portion of the packet, thus minimizing both the acquisition time and the payload's BER in the receiver.
