Please see below for how to use them properly and recommended best practices. 2. Turn on your Cuff. The Cuff will have a blue light when on. Solid blue indicates that you’re connected to your phone. BLUE Blinking green indicates charging, while a solid green light indicates the battery is fully charged. GREEN Blinking red indicates low battery. RED © Band Connect, Inc. | [email protected] Each day you log into the patient app, you will see the treatment that needs to be completed that day, including both the exercise sessions and assessments. START YOUR SESSION 1. Complete Exercise Session #1 First, select Session 1 on the assigned treatment screen to begin. Then follow the prompts to complete all exercises in Session 1. 2. Complete Additional Exercise Sessions After Session 1, proceed to the next available sessions, if any. Please follow directions from your clinician as to the interval between sessions. 3. Complete all assigned Assessments. Select “Assessments” on the treatment screen. Follow the prompts to answer the assessment questions as presented. Completing Your Treatment Need help?

Pausing your session If interrupted, select the pause button to resume later. To skip an exercise, pause and select “Skip.” Choose a reason from the dropdown menu. 2. Movement Cues While completing your therapy, you’ll see cues such as “too fast,” “too slow,” “too short,” or “too far”. These are to help guide you to recreate what you did in the clinic with your clinician. WHAT YOU’LL SEE © Band Connect, Inc. | [email protected] Completing Your Treatment 3. Adjusting Tension The app ensures that you start with the right starting tension for each exercise that leverages the resistance band. Use the app’s tension bar to match the resistance band tension. 4. Haptic Feedback Handles buzz to signal when to start, pause, or end movements. Stronger feedback indicates incorrect handle positioning or movement. WHAT YOU’LL SEE The Band Connect app is very simple to use.

Introduction This application note is dedicated to the STM32WB Series microcontrollers. One of the main reasons to use a PCB (printed circuit board) antenna is the reduced overall cost of the radio module. Well designed and implemented PCB-printed antennas have a similar performance to the SMD (surface-mounted device) ceramic equivalence. In general, the footprint for a ceramic SMD antenna is smaller than that for a PCB-printed variant. For a PCB-printed antenna solution, the increased size of the PCB in relation to space required for the antenna means that the radio module is larger and the cost of the PCB increased. However the PCB solution is generally cheaper than a SMD ceramic antenna. The demonstration and development boards for the STM32WB Series implement PCB printed antenna based on this application note. Low cost PCB antenna for 2.4 GHz radio: meander design for STM32WB Series AN5129 Application note AN5129 - Rev 4 - April 2019 For further information contact your local STMicroelectronics sales office. www.st.com 1General information This document applies to STM32WB Series Arm ® -based devices. Note:Arm is a registered trademark of Arm Limited (or its subsidiaries) in the US and/or elsewhere. AN5129 General information AN5129 - Rev 4 page 2/22 2Coordinate system For the purpose of this document, the spherical coordinate system illustrated in the figure below is used. Figure 1. Spherical coordinate system The PCB module is orientated vertically (plane X-Z) and located in proximity to the origin of the coordinate system. The azimuth angle radiates from the X-axis towards the Y-axis and the elevation angle radiates from the Z-axis towards the horizontal X-Y plane. Sometimes, as with geographical and navigational systems, the X-axis is called the "Nord-axis", the Yaxis is called the "East-axis" and the Z-axis is called the "Zenith-axis". AN5129 Coordinate system AN5129 - Rev 4 page 3/22 3Layout specification The PCB antennas, including the electrical parameters of PCB materials used, are layout sensitive. It is recommended to use a layout as close as possible to the one shown in the figure below. Figure 2. PCB antenna dimensions (in mm) The electrical parameters and performance of the PCB antenna are also determined by the substrate used, in particular the thickness of the core and dielectric constants. AN5129 Layout specification AN5129 - Rev 4 page 4/22 The figure below illustrates a typical cross-section of the substrate in a PCB-antennae area. Figure 3. PCB cross section at antennae area A substrate with the parameters as defined in the table below is recommended. Table 1. Recommended substrate specification Layer Dimensions Dielectric constant Ɛ R LabelValue (mil)Value (μm) Solder mask, topS10.717.784.4 Copper traceT1.640.64- CoreC28711.24.4 Solder mask, bottomS20.717.784.4 AN5129 Layout specification AN5129 - Rev 4 page 5/22 4Impedance matching Meander-like PCB antenna can be tuned to the required 50 Ω impedance by matching the impedance circuitry with the π topology. In Figure 2, the impedance matching area is marked with a dashed line. Under nominal conditions, this antenna exhibits and impedance very close to the required nominal impedance (50 Ω). To check the performance of this design, a sample antenna was manufactured (according to the specifications covered by this document). The figure below shows this antenna. Figure 4. Part of 802.15.4 and BLE PCB with meander-like antenna (scale around 4:1) Assuming that the manufactured sample exhibits the expected performance (no impedance matching necessary), the impedance matching circuitry is bypassed by two 100 pF capacitors connected in series, as shown in the figure below. Figure 5. Bypassing impedance matching circuitry - Direct RF connection All electrical parameters of the meander-like antenna have been measured at connection to the band-pass filter (BPF) with the frequency span covering frequencies from 2.4 GHz to 2.5 GHz. AN5129 Impedance matching AN5129 - Rev 4 page 6/22 Complex impedance of the antenna is shown in the Smith diagram in the figure below. Figure 6. Complex impedance of the meander-like antenna (Smith chart) The figure below shows the magnitude of the S11 parameter (in log scale). Figure 7. S11 parameter in logarithmic scale (Cartesian plot) AN5129 Impedance matching AN5129 - Rev 4 page 7/22 The figure below shows the standing wave ratio (SWR). Figure 8. Antenna standing wave ratio (SWR) The following changes affect the radiation impedance of the PCB antenna: • slight board size variation • metal shielding • use of plastic cover • presence of other components in proximity of the antenna The best performance impedance matching circuitry compensates these effects so that, for operating frequencies, the optimum 50 Ω impedance is achieved. AN5129 Impedance matching AN5129 - Rev 4 page 8/22 5Radiation pattern, 3-D visualization A three-dimensional (3-D) visualization of the radiation pattern (magnitude of the electrical far field |E|) is done for the center ISM band frequency 2.44175 GHz. Figure 9. 3-D radiation pattern overview Figure 10. Radiation pattern on X-Z plane AN5129 Radiation pattern, 3-D visualization AN5129 - Rev 4 page 9/22 6Radiation pattern, 2-D visualization In this section, all radiation patterns are related to the magnitude of electrical far field |E|, that is normalized and shown in the logarithmic scale (in dB). This means that the maximum global radiation pattern (maximum magnitude of the electrical far-field E) is represented by 0 dB level. To show the antenna radiation patterns in detail, three two dimensional (2-D) major cuts are presented. Consider the orientation of the module in the spherical coordinate system as shown in Figure 1. A three dimensional (3-D) far field radiation pattern is visualized as three two dimensional (2-D) cuts through a 3- D pattern. The following major planes are used for these cuts (see Figure 11): • one horizontal X-Y plane • two vertical planes: X-Z plan…
