Challenges of Aged Care Facility Oversupply A need to differentiate services emerges An increasing number of aged care facilities Despite the growing elderly population services are experiencing low satisfaction levels 2 caused by exposure to humidity in diapers resulting from neglected bowel movements exacerbates the pain of patients in the room Colon bacillus, Dysentery, Staphylococcus aureus, etc The emotional burden of not being able to personally care for the patient weighs heavily on the guardians Skin rashes Unsanitary environment Bacteria in excrement Heightened anxiety for guardians Wearing a diaper poses a potential threat. to the health of patients, not only in terms of self-esteem. Nursing care workers responsible for numerous patients face a series of challenging and painful tasks when physically assessing the bowel condition of each patient. Providing the desired high-quality services to patients and their guardians is limited by the challenges of excessive labor costs and operational difficulties. The patient’s distress with a soiled diaper is difficult to comprehend, especially when they must wait for the diaper to be changed. The moment a patient is prescribed to wear a diaper their self-esteem may be adversely affected. 3 For patients dealing with dementia, urinary incontinence, severe conditions, and cognitive impairments related to defecation, our Smart Healthcare Bowel Sensor Operation System offers improved management. This extends support not only to the patients but also to the dedicated carers, who, always concerned about their patients’ conditions, indirectly bear the burden of suffering. Additionally, healthcare workers, responsible for the well-being of both patients and guardians, find enhanced care through our system. Our Smart Healthcare System is designed to provide comprehensive assistance. 4 1. What is the Bowel Sensor Operations Management System 2. What are the benefits of the system? 3.

Product Description LORA Internal antenna for use in a portable unit for wireless communication (referred to as a radio). 1.2. Product Number LEETEK Product Name : Leetek IN-Ant-01 1.3. Units, Definitions, and Abbreviations Unless otherwise stated, SI units are used. TX Transmit Band RX Receiver Band PCB Printed Circuit Board RH Relative Humidity dBi Antenna gain in Db (isotropic) CW Continuous Wave 1.4. Interface All properties are guaranteed under the conditions that antenna/radio interface is designed in accordance with instructions provided by Leetek. Functionality with other equipment (such as couplers etc.) is not guaranteed unless this has been agreed upon separately. 1.5. Conditions Unless otherwise stated all temperature tolerances are ±3°C and all RH tolerances are ±5 percentage units. Unless otherwise stated all values are valid at 20°C and 50％ RH. 1.6. Coordinate System The coordinate system for the radio is defined as follows; . Origin in center of gravity. . Positive X axis is perpendicular to, and directed from, front plane. . Positive Y axis is perpendicular to, and directed from, right side plane(as seen from front). Positive Z axis is perpendicular to, and directed from, top plane. 2. Electrical Properties 2.1. Frequency Band 2.1.1 LORA Band : 902 ~ 928MHz 2.2. Impedance 2.2.1 Nominal Value 50 Ohms 2.2.2 Method Leetek will supply engineering assistance to ensure that the impedance Over the frequency bands is as close to 50 ohms as possible after matching. Both free space and talk position are considered, with priority given to talk position. 2.3. VSWR Below are listed the maximum values of the worst matched frequency within each band including production variation influences. 2.3.1 VSWR at Free Space 902MHz : 2.3, 915MHz : 2.2, 928MHz : 2.2 2.3.2 Tolerance of Center Frequency Center Frequency at Lora Band : Standard ±15MHz 2.3.3 Method of Measurement A 50 ohms coaxial cable is connected(soldered) to the 50 ohm feeding point on the PCB. The connection of the coaxial cable is done so as to introduce a minimum of mismatch. In the other end, the coaxial cable is connected to a network analyzer. The analyzer is calibrated so that the reference plane is at the 50 ohms feeding point.. The radio, including the PCB must not in any significant way differ from the mass produced radio, e.g. the antenna feeding parts have to be equivalent to the parts in mass production. Free space means that the radio is attached to a nonconductive surface. 2.3.3 Electrical Performance Assurance Sampling Plan 2.4. Gain Below are average gain values of the frequency with the lowest peak gain within each band including production variation influences. 2.4.1 Values Unit Lora 902MHz 915MHz 928MHz (dBi) -8.47 -9.02 -9.63 2.4.2 Method of Measurement The connection is done according to 2.3.2, Radiation patterns are measured at the TX and RX band edges for each band defined in 2.1.1 and 2.1.2. The measurements are Performed so as to minimize the influence of the cables. Only the coplanar polarization component is measured. The antenna is measure in 2 orthogonal E-planes in free space, according to figure 2.4.1. The antenna is also measured in talk position. Calibration for absolute measurements is done with a reference antenna, which is in turn calibrated by a certified calibration company. 2.5 Power Rating 2.5.1 Maximum Value P = 100mW (CW) 2.5.2 Post Test requirements Without mechanical damage and electrical performance according to 2.3.1 and 2.4.1, after the test. 2.5.3 Method of Measurement The connection is done according 2.31. The specified power, P, is applied for 10 minutes at the middle frequency of each TX band defined in 2.1.1. Immediately after the test the VSWR is measured. 3. Antenna Drawing 4. Radiation Gain
