Abstract

A brassiere which includes a number of skin temperature sensors is described. The sensors are connected to battery operated integrated circuits including storage registers, all, including the battery, integral with the brassiere. The skin temperature at predetermined intervals is recorded and can be "read out" into a printer after long intervals. Hence the brassiere can be worn normally while skin temperature monitoring is carried out at known times. It is believed that these temperature measurements when considered relative to daily and monthly bodily rhythms will be useful in detecting illness, particularly cancer.

Claims

1. Apparatus for measuring surface temperatures at points in a region of the human body, including

a garment,

a plurality of temperature sensors in the form of semiconductor junctions located in the garment at spaced apart positions,

means for storing signals representing output signals from the sensors, control means for passing said signals representing output signals from the sensors to said storing means, clock means for producing clock pulses for actuating said control means whereby the time of occurrence relationship of the said output signals stored in said storing means is retained, the storing means, control means, and clock means being integral with the garment.

2. Apparatus according to claim 1 wherein readout means are provided for connecting the storage means to data logging means external to the garment for providing a display representative of the stored signals.

3. Apparatus according to claim 2 wherein the means for storing signals includes

means for sampling the output signals of the sensors at predetermined intervals, and

storage means for storing signals representing the output signals so sampled.

4. A brassiere for measuring surface temperatures of the breasts at predetermined points, including

a plurality of temperature sensors positioned in each cup of the brassiere,

sampling means for sampling the output signals of the sensors,

storage means for storing the signals so sampled,

clock means for producing clock pulses for actuating said storage means whereby the time of occurrence relationship of the said output signals stored in said storage means is retained,

the sampling means, storage means and clock means being integral with the brassiere.

5. A brassiere according to claim 4 including

readout means integral with the brassiere for coupling the storage means to data logging means external to the brassiere for providing a display representative of the stored signals.

6. A brassiere according to claim 5 wherein each sensor is arranged to form a thermal shield to prevent heat flow from the skin where the sensor is, in operation, located.

7. A brassiere according to claim 5, incluing

a multiplexer means integral with the brassiere for coupling each sensor in turn to the storage means when a clock pulse is received by said sampling means.

8. A brassiere according to claim 7 where

the multiplexer means couples the sensors to the storage means by way of a sample and hold circuits and an analogue to digital converter.

9. A brassiere according to claim 8 wherein the storage means includes

a first shift register and

a second shift register of relatively large storage capacity compared with the first shift register,

the first shift register being coupled to receive digital signals from the analogue to digital converter,

and the second shift register being coupled to receive digital signals from the first shift register.

10. A brassiere according to claim 5 in combination wih display means, external to the brassiere, for displaying the said stored signals.

11. A brassiere according to claim 10 wherein the display means displays the stored signals by printing.

12. A brassiere according to claim 4 wherein said storage means, sampling means and clock means are positioned in a plurality of packages spaced apart from one another, and integral with the brassiere.

13. A brassiere according to claim 12 including a rechargeable battery mounted on the brassiere.

14. A brassiere according to claim 4 wherein each sensor comprises a semiconductor junction.
