Abstract: A hookah device (202) which attaches to a hookah (246). The hookah device (202) comprises a plurality of ultrasonic mist generator devices (201) for generating a mist for inhalation by a user. The hookah device (202) comprises a driver device (202) which controls the mist generator devices (201) to maximize the efficiency of mist generation by the mist generator devices (201) and optimize mist output from the hookah device (202).

Abstract: A mist inhaler device (200) for generating a mist comprising a therapeutic for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

Abstract: A disease screening device (100) comprising a substrate (101) and a sonication chamber (102) formed on the substrate (101). The sonication chamber (102) is provided with an ultrasonic transducer (105) which generates ultrasonic waves to lyse cells in a sample fluid within the sonication chamber (102). The device (100) comprises a reagent chamber (111) formed on the substrate (101) for receiving a liquid PCR reagent. The device (100) comprises a controller (23) which controls the ultrasonic transducer (105) and a heating arrangement (128) which is provided on the substrate (101). The device (100) further comprises a detection apparatus which detects the presence of an infectious disease, such as COVID-19 disease.

Abstract: A mist generator device (400) for delivering a mist to a user, the mist generator device (400) for use with a driver device (202). The mist generator device (400) comprises a housing (204) comprising a liquid chamber (218), the liquid chamber containing a liquid to be atomised, the liquid comprising a therapeutic. A sonication assembly (425) is coupled to the housing (204) the sonication assembly (425) comprising an ultrasonic transducer (215), a first assembly portion (426) and a second assembly portion (428) coupled to the first assembly portion (426). At least one of the first assembly portion (426) and the second assembly portion (428) comprises a resiliently deformable section that forms a seal between the first assembly portion (426) and the second assembly portion (428) which minimises or prevents a fluid from leaking between the first assembly portion (426) and the second assembly portion (428).

Abstract: An infectious disease screening system (1) for screening for infectious diseases, such as COVID-19 disease. The system comprises an ultrasonic transducer (49) for generating ultrasonic waves to lyse cells in a biological sample. The system (1) comprises a controller which controls the ultrasonic transducer (49) to oscillate at an optimum frequency for cell lysis, a PCR apparatus (16) which receives and amplifies the DNA from the sample; and a detection apparatus (70) which detects the presence of an infectious disease in the amplified DNA and provides an output which is indicative of whether or not the detection arrangement (70) detects the presence of an infectious disease in the amplified DNA.

Abstract: A nicotine delivery device (200) for generating a mist containing nicotine for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

Abstract: A bearing arrangement comprising a housing, a liner positioned within the housing and providing a bearing surface; at least one sensor within the liner, positioned at a predetermined depth beneath the bearing surface, configured to detect wear of the liner to said predetermined depth.
